Removing SWAP - G1 Q&A, Help & Troubleshooting

Removing SWAP - G1 Q&A, Help & Troubleshooting

I am running the latest WES Build Y .. He stated that SWAP slows down phone and in his next release, he is going to remove SWAP.. Just curious how do i follow up on making sure swap is not enabled..
I have User.conf, and the other user.init on the SDCARD and i also have a HUGE file @ 62MB that is called something like SWAP???? ... If i delete all three will that remove SWAP completely?

I would remove the swap file and the swap partition. The user.conf and userinit.sh do more than control swap

remove the partition too... ??
Therefore, I would have only 2 partitions.. ( Fat32 and Ext3 )
That right ?

Yeah, but if you don't want to repartition you'll have some empty space on your sdcard (how ever big the swap partition is) until you do partition again

need help pls dont kill me!

hello all first post and hopefully last post... I have tried to search and search and read and read but still confused on some things. I just have a few questions the confusion comes from instructions how to do things but no reason or explanation why. so anyways here goes I started with no knowledge of any of this so I dont need help with root, and flashing roms or installing and using adb... I have a G1 with pvt board I also plan on using just the linux-swap for now not the compcache one so here goes
1) what is the difference in partitions (ext2 ext3) what is each needed or used for? like your main fat32 is for storing apps and data? one is a ram swap kinda like virtual memory? I just not sure if I would need ext 2 or ext3 or both...I am using hero roms... does the linux-swap partition count as a ext2 or 3? and lastly why do u need to convert a ext2 to and ext3 you cant just create an ext3 off the bat?
2) how do I know if the rom does not say what type of swap it is using as in comp or linux swap? I have read about the user.cfg file but kinda unclear in that... do I have to edit it or just check it from the zip file and see the settings? if so I see downloads for a user.cfg (of course prolly not the settings I need for that rom) but I just edit it and throw it on fat32 partition and it should work automatically? if the rom has compcache working can I still disable it and just use a linux-swap and just change the size of the swap?
3) what is the difference between the user.cfg and userinit.sh?
4) after the rom is flashed (my update.zip) it is ok to delete it off the sdcard?
5) so lastly if I want to put pics / music / videos do I just throw them on the fat32 partition but in what folder so it recognizes it? or do I need to download some kind of file manager to get into the flashed rom so I can see the correct media / download / camera folders and place them there? if I have to go the latter route do I need to do the whole adb "push" thing to get them in there? reason why I ask is with a normal G1 when you connect it with the data cable to your computer i can just see the folders but when rooted and flashed obvioulsy there is nothing to see
6)apps2sd runs and saves on what partition?
please dont kill me I honestly did search and read all over just seems confusing most of the "guides" tell me how to do things but I dont know why those things are usefull or needed to be done

1) EXT2 and EXT3 are linux filesystems. If you have an EXT partition on your SD card then this is where apps will be stored. You may notice that if you're running a Hero ROM with no A2SD (/Apps2SD) you will only have about 20mb left for apps. You can make this linux partition as big as you want (within reason). Most people use 512mb, because it's all the space you will ever need for apps.
On to the differences between ext2, ext3 and ext4. Most people use ext3, the reason being is it uses journalling, making it faster and more efficient than ext2. There's nothing wrong with ext2, but ext3 is just a bit better. All ROMs with A2SD support will lit you use ext2 and ext3. Ext4 is less well supported. Personally I use it, just because it's newer than 3, but it's not supported by all ROMs.
So, just got for ext3.
Linux swap is totally different from ext filesystems. As you suggested it is virtual memory, which is essential on Hero ROMs. Personally I use a 64mb partition.
So my 8GB card looks like this
FAT32 - 7.5GB
EXT4 - 500mb
Linux-Swap - 64
2) I think you mean user.conf and userinit.sh. These files tell the ROM what settings to use for Swap and CompCache. It's not essential, just ignore it.
3) user.conf and userinit.sh work together. userinit.sh is one you edit, and user.conf initiates userinit.sh. Again, no ROMs require this, don't worry about it.
4) yeah you can delete update.zip. Personally I keep all my ROMs on the root of the sdcard so I can flash/reflash whenever I want to.
5) You put media on the phones Sd the same way as if it was not rooted. Connect the cable, pull down the notification bar, choose "mount" and drag and drop your files over. Windows won't see your ext partition btw.
6) Apps to sd saves to your ext partition, be it ext2/3/4 ect.
Sorry for the long post just wanted to make sure I answered everything.

3) user.conf and userinit.sh work together. userinit.sh is one you edit, and user.conf initiates userinit.sh. Again, no ROMs require this, don't worry about it.
should be user.conf you edit

actually i think you have this one backwards Adrian. the userinit.sh is what the a2sd script makes a call to upon every boot to activate your linux-swap partition and it uses the various system defaults usually, the userinit.sh then makes a call to the user.conf to see what values it is suppose to use for the various things if they are different then the system default values, and will use the ones in the user.conf. user.conf is the one you edit to change the various values.
or at least this is my understanding of how it works.

ok so basically I just open the zipped rom and see if there is a userinit.sh file in there which means apps2sd is already in the rom... then look at the user.cfg... but do I try to edit the user.cfg before I flash the rom and re-zip it then flash or am I able to edit the user.cfg after I have flashed the rom... I know I believe I am supposed to use the notepad++ to edit it from unbuntu live or is there another way to do it? when I connect and mount my phone in normal working mode not (terminal or console mode) all I see is the update.zip file on there I can not see any of the ext partitions is that normal? as in you can only see your fat32 and what files (music pics) that you put on there? is there any way to view the ext partitions?
like I said if I have an edited user.cfg file with the settings I need do I need to "push" it to the flashed rom via adb? or would it be easier to just edit it then re-zip then flash? oh and by the way what is the direct path to the user.cfg and userinit.sh? as in what folders do they normally reside in?
THANKS you guys are seriously helping me alot soon I will be cooking my own roms.... I just need an understanding of these things not just guides telling me to type stuff even though they work doesnt mean I know whats going on
btw I am trying to use MLIGN-HeroV2.1.6 rom and super laggy for me so I know the partoition sizes are wrong or not working correctly or swap is not enabled....and yes I have an 8g transcend class 6 card... all the others in the thread say its very fast with no major home screen lag and such so I messed up on settings and partions

you must put the userinit.sh and user.conf in /system/sd (your ext3) and chmod 755 both of them.
there are good instructions for using and editing them in the link dan0zone gave you.
the userinit.sh and user.conf (as far as i know) do not come standard in roms, the a2sd scripts reads and runs them on the first boot, more technically the a2sd sends a call out to see if there is a userinit.sh then if there is and if it is the userinit.sh from that link, it then looks at the user.conf to see what values it uses.
i always use pspad to edit my user.conf (and any other android related file) in windows. here is a link to pspad.

Adrian had it right except for the flip flop between user.conf and userinit.sh. You don't want to edit userinit.sh unless you know what you are doing. The user.conf and userinit.sh files are not in the ROM itself. They need to be pushed to /system/sd via adb or terminal emulator. See my signature for the link to the details.
You will not see your ext3 or linux-swap partitions in Windows. You can use adb shell, terminal emulator, a root explorer or Droid Explorer to see those.
Also, if you'd like to edit your user.conf right on your phone, download Text Edit free from the Market.
Here's a big tip. Investigate two scripts. One is called switchrom.sh and the other is called bart.sh which is an update to switchrom.sh. It will save you a lot of headaches later on.
Hope I got it all.

man you guys are great thanks for the replies I think I understand it all now. I will try the pspad and see how that works out although the text edit free seems like a more easier way if your not around a computer... the question I have if I path to /system/sd what if I have an ext 3 and 4 which one would it end up in? ext2 it wont I assume? in some guide I read they say to just put it on the sd card like as in the fat32 part which I know is wrong! or they just didnt explain in further details.... oh god didnt want to get into the chmod 755 cause I didnt think I needed to do that now I will have to go figure out what that does and its purpose... there has been many thread arguments over wether to use chmod 755 I just thought a linux-swap about 96 or so with a swappiness setting of say 60 would be fine didnt think I would need to enable or set up chmod 755
thanks so much!!
dan0zone's link I have read before i can download the userinit.sh file but have no user.cfg to play with are the user.cfg all standard or generic until I or someone else edits them? where can I get a user.cfg file was not in the link dan0zone posted

chmod 755 = -rwxr-xr-x = for a regular file whose user class has full permissions and whose group and others classes have only the read and execute permissions.
there you go. /system/sd is what the directory associated with /dev/block/mmcblk0p2 which is what your ext2/3/4 (doesn't matter) is.
the only thing you need to chmod 755 are the userinit.sh and the user.conf after you place them in your ext2/3/4 partition, and the reason is so that they may run after being called by the a2sd script at boot up.

ok thanks about the chmod 755 I believe i get it seems to be a permissions thing....
any answer on the user.cfg file if it is a generic template file or where to get one unedited?
thanks for the switchrom and bart tip I totally understand that but for now I dont have anything I need to save and backup just doing it bare but in the future i will use those on ce I get better at all of this.... which thanks to all of you i am understanding this ALOT better.....

you can get one from the link that was provided earlier, it shows what the system defaults are beside each of the settings, so if you want to set it all to the system defaults then you can.

ah sorry I am stupid I just saw the title of the userint.sh file I didnt open it too see there was a user.cfg in it.... thanks
I plan to repartition and setup the userinit and user.cfg all over again this is probably the worst question yet but I just plan to stick my sd in my computer and reformat the whole card is that enuff to completly wipe it or will the ext and linux-swap still be in there?

if you are using windows then it will only format the fat32 partition, to get your card back to one partition, you can use parted in the recovery console to rm your partitions then make a single fat32 partition or just rm all partitions then re-make them to whatever size you want.

You can also format your sd card (wipe everything including partitons) by going to Settings, SD Card, Unmount, Format/Erase (not sure what it's called). This seems to work sometimes. You should use parted anyway since you will need to repatition your card there so no need for the extra step. BTW, it's user.CONF not user.CFG. just a heads up if you plan on searching. My signature has all the necessary links to pretty much everything you will need.

AFAIK if the rom has a2sd included, you wont have an option to unmount the sd card.

Indeed you are correct, sir. I haven't done it this way since the JF1.51 days. I use either parted command line or GParted on Ubuntu so I didn't even check the settings when I wrote that.

FINALLY got cyanogen rom working. i've almost pulled my hair out over buying this phone(att user so i had to unlock and learn root, etc.)
anyways, got .999 installed and saw the * Apps2SD is automatic! All you need is a second partition (ext).
can someone point me in the right direction on how to do the partition part? i have full version of paragon and know how to use it but just don't want to fubar anything up.
i apologize for the noob question but i just need to know what to set my 2gb(although i have a 4gb class 6 in the mail now) sd card to what size partitions so i can run the add2sd.
thanks guys and love the site.

There is a sticky post in this section. I found it in less than 2 seconds. without searching.

Example for 8GB card.
Reboot and enter recovery (home+power) then go to console. Enter the below pressing "enter" after each line.
Code:
parted /dev/block/mmcblk0
print (to verfiy we know what size card we are dealing with. Mine was 8166 read below if yours is different)
rm 1 (if you had more than 1 partition you would want to rm them as well)
mkpartfs primary fat32 0 7622
mkpartfs primary ext2 7622 8134
mkpartfs primary linux-swap 8134 8166
quit
upgrade_fs
recovery
NOTE: this will reformat your entire card, so i suggest you back up your files.
and btw tell me the size of your sd card and i will type up the code for you...
use this method to tell me your exact size
go into recovery via home+power
go to console
pres enter
type:
parted /dev/block/mmcblk0
print
i am pretty sure you can see what number represent your total card size.

Easier Way!!!
OK,so I also have Paragon Partition Manager 9.0 Special Edition.
1.Go into your Paragon Partition Manager Software
2.Click on Partition Manager at the first screen
3.Click on your SD Card drive (ie. F:/)
4.Click on create partition in the left hand side of your screen.
5.It will ask you how big you would like your partition to be,then what type of partition. Paragon only supports EXT2 and EXT3 if your looking for an EXT partition. Paragon also only supports Linux-Swap2 and not Linux-Swap3.
If you need any more help man let me know.

well i wouldnt say ur way is easier... it does require using a computer, mine uses the phone.. and mine is simply typing what u see.

Also im pretty sure you need to use linux-swap and not linux-swap2
(i think 2 works but im not sure that its recommendable sicne the rom cookers themeselves use 1)
I would also use the method brian posted. its much more effective

thanks guys, i got adds2sd working and everything. on a 1gb right now until my new 4gb class 6 comes in this week.
i haven't done the swap things yet as i'm not sure of them just yet. i've learned quite a bit over the last week without trying to bug too many people on the forum. your replies are MUCH appreciated.
what is the different between ext 2/3 and linux-swap? i'm running my current 1gb 514mb fat32 and 445mb ext3.

ext3 has journaling which reduces corruption a lot. linux-swap is used as virtual memory.

thanks for the reply so in turn the swap will make the phone run faster right?
also, since no one answered my question in another thread:
although i'm running .999 when i press the camera button it open a box with a 'To:' entry and 3 button 'open', 'call', and 'send'.
i've looked in the settings to see if i can change what the camera button does(want it to open the camera like before obviously) without any luck..
any idea?

In theory swap should make it faster as it has more memory to play with.
For your other question, a file on the ROM containing the keymaps has been changed. The only way to change what the camera button does is pull it, edit it, and push it back.

Linux-swap Cynanogen?

ok so i made a linux-swap partion on my sd card that is 64mb. Now do i need to activate it somehow? or does cynogen do it for me? i tried to search but couldnt find. also do i need update my radio? it is 2.22.19.26I

You need user.conf and userinit.sh files on your ext partition. There's a guide on how to set that up here.

ok and can i have compcache and linux-swap at the same time? or do they do the same thing? also do i need to make a partion for compcache? and i cant find the htc keyboard in 4.2.3.1, does it come with it?

i thought if you have 4.2.3.1 you didnt have to add the files as it does everything for you? am I missing something.

is compcache and linux swap the same thing? and do we need both?

lol, no.
Swap is virtual memory. It uses a seperate partition to act as extra RAM, but it's nowhere near comparable to real RAM.
Compcache compresses what's in the RAM, so there's more space to cram files in. The problem is constantly compressing and decompressing files in RAM puts a heavy strain on the CPU.

so do i need to put the usernit files on or did this rom already do it?

does anyone know how to use the user.config app to do this?

You DO NOT have to add any user int files to your sd for swap to work.
Its already rolling if you installed correctly.
go to terminal and use the print command to view your allocated spaces for each ext

Better yet, use the "free" command to see if it is really being used. I am pretty sure Cynanogen does not use a swap partition by default. It needs to be enabled. A easy way to check and setup your swap it to download swapper.

When I type free in the terminal I see 0 for total, used and free swap. I made an ext4 and a 32mb swap partition on my sd card. How do I enable swap on Cyanogen 4.2.5?

Partition SD card on Windows for people who can't be bothered to do it properly ;)

Firstly, BlaY0 has a great tutorial on how to do this properly, I suggest you do that to learn something.
Secondly, I cannot confirm that this is 100% safe. BlaY0's method should be 99% safe, I don't know about this as it is all automatic. BlaY0's method is tried and tested, this is not. I only used this method as I had a new SD card and I was in a hurry (exams coming up ) and I didn't have time to remind myself of BlaY0's method, and CWM only allows you to create up to 512mb partition. Also, I had a new computer, and I don't have time to set up ADB all over again.
Anyway, this is a method for people who don't want to use ADB to partition their SD card for A2EXT or DATA2EXT (a.k.a. apps2sd, etc etc), and are using Windows. If you're running linux, you could use something like gParted to partition it, not sure about OS X though. This method will allow a Windows user to create an EXT partition on their SD card alongside the FAT partition.
1) Download and install Minitool Partition Wizard, from here.
2) Open the program and delete all partitions from the SD card (which you will have inserted into the computer using an adapter or something). DO NOT DELETE THE PARTITIONS FROM THE HARD DISK! MAKE SURE YOU KNOW WHAT YOU'RE DELETING. Oh, and make sure the SD card is backed up
3) Create a FAT32 primary partition. You decide how big you want it, but I'd advise you leave 1024mb (1gb) for the EXT partition.
4) Create an EXT2/EXT3/EXT4 (you decide) primary partition. Use up the rest of the space on the SD card.
5) Click assign/OK/whatever and wait for it to complete
6) You now have your partitioned SD card ready for an A2SD ROM!
7) You need to assign a drive letter to the FAT32 partition. Not sure about the EXT partition. At first I forgot to do this and my card didn't show up in Windows, though Partition Magic can still see it.
Like I said, do yourself a favour and use BlaY0's method here, but if you're lazy or you don't have time or ADB doesn't work anymore, use this.

Nice one m8. You mentioned that CWM doesn't offer adding partitions bigger than 512 MB. Well, you're right but that's why I made a customized version of fake-flash that can do bigger... to 1 GB. It can even add second ext partition for some exotic types of data2ext. On top of that I added auto block alignment which is described in my guide (the manual one) so no more calculations and manual labour

Didn't know that, good to know, for those of us still using data2ext, this is important...

Wish this was up earlier, spent an hour repartitioning my card using parted.Couldn't upgrade to EXT3 and ended up using CWM 3.0.2.8 to do it instead lol

What CWM is using under the hood for partitioning is actually parted.

Tried it but it didnt work not sure what the problem is...
formatted my SD to FAT 32 and reserved 1G for EXT3 both as primary partition in the Mini Partition Tool
Plugged it in my phone,
Ran ADB shell
# a2sd --enabled, rebooted
on reboot nothing seemed to have changed... went back to ADB shell
tried a2sd --free it says A2Sd is not active ...
a2sd -- enabled again and it says it is enabled but not active
so im guessing it cant read or recognize the EXT3?!
Any clues... i didnt want to move my Dalvik to SD ... should I try EXT4 or even EXT2?

Take me through what you did, step by step. You say you reserved 1G for EXT3, but did you actually format it as another partition?

It has been mentioned here like a gazilion times, boot up your device with logcat and see the first few lines...there is your answer!
Google how to wait for the device with logcat

1) Downloaded and installed Minitool Partition Wizard from your link. I got the free home edition
2) backed up my SD card and Open the program and delete my SD card partition ( which is in a card reader)
3) Created a FAT32 primary partition of 69xx MB and left the rest 1024 MB for the other unallocated space
4) Right click on the Unallocated Space to create an EXT3 as primary partition with the default cluster size.
5) At this point, it showed 2 partition on my SD, one with the drive letter for windows FAT32, and the 2nd one Ext 3 with 1GB and Primary. Clicked OK and Apply and wait for it to complete.
6) once complete , put it in phone, plugged usb and ran adb shell
7) ran a2sd --enable, it said reboot phone.. i made a mistake to reboot by adb the first time but then did the whole process again a 2nd time using reboot from the phone....
Tried logcat using this command "adb -d logcat>mylogfile.txt"
couldnt find the file anywhere ... if i dont redirect to the txt , it goes too fast to read and there's soo much debug messages what do i need to look for?
I thought it would save me time to get it done through windows... but its taking me as much time it w0uld probably get me with the manual way...
i'll give it a try tomorrow...
8) rebooted fine, and i was still low on space.. so went back in adb sheel to check a2sd --free but this is where it says not active..

Tbh I'm really not sure. One thing I forgot to mention in the guide is that you should assign a drive letter to the FAT32 partition or it won't show up in Windows. I didn't assign one to my EXT4 partition though, and DATA2SD is working great for me. Try deleting all partitions from the SD card and start again. It'll only take 10 minutes, and if it still doesn't work just use the manual way.
Sorry.

Yeah i assigned a drive letter to FAT32...
Also the FAT32 , was my first block allocated partition, the 2nd partition was EXT3... i will redo the whole process and recreate EXT4 instead.
"DATA2SD is working great for me" ... you mean "A2SD working great for me" ... right? unless i'm missing something else that i needed to run..
ps: I recalled, after it was not working, i took out the sd and put it back in the reader to open MiniTool, it showed EXT2 instead of EXT3 ( which i was sure i chose )... and what's weird is it was reporting used space like 41MB... so obvisouly, the ROM wrote something on it...
Formatting it again to EXT3, didnt delete the 41 Used space, but it did convert it back to EXT3 ...probably nothing but mentioning as well

I suggest you start over, something seems to have gone wrong.
A2SD is where the apps are stored on the EXT partition.
DC2SD is where the dalvik cache is also stored on the EXT partition.
DATA2SD is where the entire /data partition on the phone is stored on the EXT partition of the memory card.
Partitioning the SD card with a FAT32 partition and EXT partition is done first, then you decide which one is for you. DATA2SD does have one or two issues, such as the risk of corruption - you'd then have to completely reinstall the ROM. A2SD and DC2SD are fine but I still found myself running out of internal memory.

i gave up and used ROM Manager to create my partition ...i couldnt set it to 1G because 512MB is maximum but it was painless to create.
it asked me to create a swap partition... i've read somewhere that swap partition is useless or barely used in newer android os? do you guys have any swap partition if so how big are they?
Also, did you move Dalvik cache to sd? isnt it slower on SD? i mean shouldnt dalvik cache be on RAM whihc i assume is faster than any external sd?
thanks for your insight

I used the full DATA2SD, which includes Dalvik2SD.

ok so sorry for a double post but im having an issue partitioning.
32 gb card san disk brand new
primary Fat32 10gb
primary Ext2 rest of space
once mini tool is done it sats successful but shows the sd card as Bad disk?!?
is there somthing im doin wrong? is used this guide here http://forum.xda-developers.com/wiki/SD_card_partitioning
all help deeply appriciated
Acer Iconia Tab A110 rooted, Cwm, 4.1.2

Can you actually have a 22gb ext partition? This might be something to look into to see if you can do it.
Edit: this got me interested so I searched myself, yes you can but apparently it depends on the chosen block size and hardware limitations, so u may have an issue with either.

Firstly, BlaY0 has a great tutorial on how to do this properly, I suggest you do that to learn something.
Secondly, I cannot confirm that this is 100% safe. BlaY0's method should be 99% safe, I don't know about this as it is all automatic. BlaY0's method is tried and tested, this is not. I only used this method as I had a new SD card and I was in a hurry (exams coming up ) and I didn't have time to remind myself of BlaY0's method, and CWM only allows you to create up to 512mb partition. Also, I had a new computer, and I don't have time to set up ADB all over again.
Anyway, this is a method for people who don't want to use ADB to partition their SD card for A2EXT or DATA2EXT (a.k.a. apps2sd, etc etc), and are using Windows. If you're running linux, you could use something like gParted to partition it, not sure about OS X though. This method will allow a Windows user to create an EXT partition on their SD card alongside the FAT partition.
1) Download and install Minitool Partition Wizard, from here.
2) Open the program and delete all partitions from the SD card (which you will have inserted into the computer using an adapter or something). DO NOT DELETE THE PARTITIONS FROM THE HARD DISK! MAKE SURE YOU KNOW WHAT YOU'RE DELETING. Oh, and make sure the SD card is backed up
3) Create a FAT32 primary partition. You decide how big you want it, but I'd advise you leave 1024mb (1gb) for the EXT partition.
4) Create an EXT2/EXT3/EXT4 (you decide) primary partition. Use up the rest of the space on the SD card.
5) Click assign/OK/whatever and wait for it to complete
6) You now have your partitioned SD card ready for an A2SD ROM!
7) You need to assign a drive letter to the FAT32 partition. Not sure about the EXT partition. At first I forgot to do this and my card didn't show up in Windows, though Partition Magic can still see it.
Like I said, do yourself a favour and use BlaY0's method here, but if you're lazy or you don't have time or ADB doesn't work anymore, use this.

Hahah! Thanks for you detail guide. It is so helpful for me!

what is need partition SD card?

"Its recommend to partition your sdcard before flash"
whats the use?..........

you can use cwm with the phone or minitool partition wizard with the pc

the rom maybe containing a2sd script that's why it need a second partition do it there is no harm

What size this partition should be? 100MB is enough?

atleast 512 mb for ext parttion you should create a swap partition of 256 mb,
swap will replace the ram according to the swappiness set by you

So it should be 2 partitions: one with 512 MB and another with 256 MB... The one with 512 should be formatted ext4? and the other swap (of course)?

Set it as ext2, it's faster.

Here's some info on how Linux (and thus Android) uses swap. http://www.linux-tutorial.info/modules.php?name=MContent&pageid=89
I wouldn't bother with it on a phone since Linux will just swap unchanged files right back to where they are on the phone storage without the need for a swap file and since it's unlikely that you'll ever multitask large user files on it there really is no need for it.

For what? Who is changing large data files on their phone? In all likelihood it will cost you more memory to have a swap file than it will save you memory since it won't be used.
Linux won't use it at all if the file in memory hasn't changed since it was last read from storage, it will just swap it back to where it was last read, that is, if you have an app open and more memory is needed linux will first check to see if the file has been changed since last read and since it's an app it will just link it back to where it was read from in the first place rather than to put yet another copy in swap.

am not talking about swap file am talking about swap partition and if you think there is no need then why are there paid apps like swapper for root and why are people paying for them.
suppose you are playing shadow gun with help of cf3d after the play you find that all the app like launcher background working apps are stopped due to low ram but if you have swap then the app's memory will move to swap partition and it will not close
when I had mini I had a swap partition of 512 MB and it was really working and if you think the life of SD will decrease then you should know that it has a veeeeeery lil effect on life so don't worry there is no harm

Thank u for this useful thread..

Whether you use a swap file or partition is irrelevant, Linux can use either and they work exactly the same.
In your example, all the apps would be swapped RIGHT BACK TO WHERE THEY ARE STORED since they did not change since last read, the swap would be unused and the apps would still be swapped.
I don't know if it's that you fail to comprehend the simple subject or refuse to read both what i post and what i link to but you are not understanding this.
Of course it won't affect the SD cards lifetime, it won't be used.
