Tweak init.d script prevents boot

Hello everyone!
I made this script for myself from stuff I found online. But when I put it into init.d the phone stops booting before the cyanogen logo comes up (on the second LG logo). I can't figure out why... However it works (the settings are applied) if I run it with adb once the phone is booted.
This is the script:

user.feature.lgdrm=false disable DRM Service, so you can not use the default phone ringtones and notifications but if you are planning to use your custom files without DRM then there are no problems.

Proper executing of sysctl.conf during boot

Edit: For some strange reason it suddenly works after posting this topic.. :') Delete please
Ok so this is the deal, I'm currently working on broodKernel v1.2 (yes not 1.1 but 1.2) and I've noticed that sysctl.conf isn't loaded in any way, I tried loading it with "sysctl -p" and also with su -c "sysctl -p", both tried it in the kernel itself and in init.d scripts, for some reason it doesn't load on boot, but when I load it myself with "su -c "sysctl -p" it works correctly :silly:
mode is: 644, also tried to chown it to system and/or root, both didn't work. then I question myself. is my init.d method correct? Is it running in root mode? I use this:
Code:
service initd /system/bin/logwrapper /system/xbin/busybox run-parts /system/etc/init.d
oneshot
doesn't it need a "user root" at the bottom?, I feel kinda like this emoticon ":silly:" to ask such question, but I really don't know why it's not running correctly, anyhow the sysctl values from the latest thunderbolt seem so unrealistic?:
Code:
vm.dirty_expire_centisecs = 3000
vm.dirty_writeback_centisecs = 500
But ok that's the thunderbolt settings, also I'm not sure if this really improves the system, I've noticed that the first few benchmarks score pretty high but then suddenly the sdcard read/write speed gets screwed by something.
Anyway, here are the scripts (so far):

What's the fastest ROM to date?

Finally got a new battery after over a year of not using my Droid 4.
Flashed latest CM13 nightly, 1.4ghz OC. Everything seems slow.
My 512mb ram single core $19 cheapo runs smoother.
Anything I do has a half-second or so delay, clean install with nothing running in the background.
Ideally I would just go back to some minimal 2.3.7 ROM, but compatiblity for new programs is getting iffy.
So, as of 2016, what has the smoothest ROM to do date been?

I'm running very, very debloated, overclocked stock JB 4.1.2 with Greenify and ram manager and it works pretty well. Even most of new games and emulators rund good.

Cyanogenmod 11 is quite good. One thing I noticed is that the virtual ROM slots are extremely slow, due to the loopback devices.
One way to go is to install the ROM to the virtual ROM slots to test if they are working correctly and then install it into stock slot for real use.

Up, same question here

I use cm11 or cm12 (i find cm13 extremely slow) But with the following tweaks made from my daily experience feel free to try it

Thank you man, this script made my droid 4 a whole lot more responsive and it does not reboot every few hours anymore.
Quite a few commands in that script don't work, probably due to different paths (sio plus as io scheduler and stock rom boot slot), but those that work, really seem to help a lot.
Oh and you should update the comment in that script about the zram size.

Was testing on different Kernels that's why the paths are wrong.. Please replace the sio plus with cfq or bfq (i forgot to change that)
I am glad that those tweaks help you

What about this one? Mentor's ROM http://forum.xda-developers.com/showthread.php?t=2122709
That's what I found on my used Droid 4... should I give it a try?

why replace sio plus? I used bfq before, but when i googled for sio plus i only found people saying that sio plus was the best of them all.

If your kernel support sio plus, of course use it.. else cfq or bfq is a good alternative

What am I supposed to do with these lines? And can somebody please explain what they are doing specifically?
I was trying to find a way to enable zram to cope with the small amount of memory. swap ram is an alternative, but i heard zram is faster and not stressing the storage like swap ram would.

/system/su.d

Hello. I found same questions in other topics, but couldn't find answer.
I would like run script from /system/su.d folder:
Code:
#!/system/bin/sh
echo 0 > /sys/fs/selinux/enforce
or
Code:
#!/system/bin/sh
setenforce 0
and I even tried to run test script:
Code:
#!/system/bin/sh
touch /data/local/tmp/test.txt
echo "test" >> /data/local/tmp/test.txt
But no one of them works. I tried different names for files, gave different chmod (644,700,755). Nothing helps me to run script.
Mb somebody can give me advice what's problem can be?

The file is called 00mountsd and is used to give access to exfat microsd on stock android 5.1 running on a Chuwi Hi10pro tablet with cherry trail z8350 cpu. I used this on a previous version of the tablet and it worked fine although that tablet came with RemixOS.
The file runs without errors when run manually and succeeds at it task
ls -lZ returns this -rwxr-xr-x root root u: object_r:system_file:s0 00mountsd
I'm running SuperSU Free v2.79 everything else works fine.
Any ideas?
