One of the fun things you can do on your Android device, is to play around with different ways of getting a real distro (Debian, Ubuntu etc.) working along side the Android system. There are several (A lot) of tutorials in here on how to do this, so this part will not be covered here. This thread only contains some scripts that will help make it easier working with the chroot.
Most of the scripts that comes with the endless pool of chroot tutorials, is only made to mount and unmount the distro image in the most simple way. But nothing that helps walking in and out of the chroot without mount/unmount, and nothing that takes different services, busy devices etc. into consideration.
The debian.sh script in this thread has many tasks. It will on execution check to see if the image is mounted or not. If the image is mounted, it will just enter the chroot. If not, it will mount the image and then enter the chroot. On exit it will provide you with the option of exiting the chroot or exit and unmount.
Also it provides 4 custom scripts that is placed and executed inside the chroot. One for mount, unmount, enter chroot, leave chroot. This makes it possible to control chroot services much easier.
The script debian.sh is executed using the command "debian". You can also unmount the chroot from within the android shell by executing "debian unmount" instead of entering the chroot and then exit choosing to unmount.
The unmount process has several and different unmount attempts in case of busy devices, running services etc. which will make sure that the chroot is successfully unmounted.

By default debian.sh will look for /mnt/sdcard/debian.img and mount it at /data/debian
The script has build-in first-time-install functionality that will create missing directories etc. Just change the variable "FILESYSTEM" in debian.sh to the correct path and filename of your distro image, and it will handle the rest.
Chroot Init Scripts
Inside your chroot, you can create the directory /etc/init.chroot and create the fallowing files.
rc_mount.sh - Executed after mount
rc_unmount.sh - Executed before unmount
rc_enter.sh - Executed when entering chroot
rc_leave.sh - Executed when leaving chroot
Here are an example of a mount and unmount script used to control tightvncserver.
File: (chroot) /etc/init.chroot/rc_mount.sh
Code:
#!/bin/sh
# Make sure that the vncserver is completly stopped before starting.
if [ ! -f /tmp/.X11-unix/X1 ] && [ ! -f /tmp/.X1-lock ]; then
# Start vncserver
vncserver -geometry 800x480 :1
else
# This is in case something went wrong the last time
# it was shut down. Perhaps an uncomplete unmount.
vncserver -kill :1 2> /dev/zero
unset /tmp/.X11-unix/X1 2> /dev/zero 2> /dev/zero
unset /tmp/.X1-lock 2> /dev/zero 2> /dev/zero
vncserver -geometry 800x480 :1
fi
File: (chroot) /etc/init.chroot/rc_unmount.sh
Code:
#!/bin/sh
# Only stop this if it is started
if [ -f /tmp/.X11-unix/X1 ] || [ -f /tmp/.X1-lock ]; then
vncserver -kill :1
# Make sure that these are removed
unset /tmp/.X11-unix/X1 2> /dev/zero
unset /tmp/.X1-lock 2> /dev/zero
fi
Using these scripts, the VNC Server is started on chroot mount and stopped on chroot unmount. You can still leave and enter the chroot keeping the VNC Server running.
This is simple linux script I've made to separate all apps from one big zip file made by Helium sever -> PC download. Helium wiki says to don't try to do anything with this file, but I didn't want to restore all that stuff that I've backuped before bootloader unlock on my nexus 4. I'm sure it can be writed better, but it's working
Just place script file and unziped backup folder (must be named "backup") in one directory. After execution of the script everything should be ready to copying to carbon folder on your sd card/internal memory and restoring like after normal backup.
Tested on Ubuntu 14.04.
I'm not responsible for data loss or any other problem. Use at your own risk.
Constructive criticism welcome.

I present you universal script to enable Init.d in ALL ANDROID DEVICES (I hope...) while running the stock kernel. NO BUSYBOX needed! It is packed in easy to use ZIP flashable
EDIT: This script will NOT work with Magisk! However, notice that using Magisk you do not need init.d support at all (you can put your scripts in /magisk/.core/post-fs-data.d OR /magisk/.core/service.d, depending on your needs).
Requirements:
- a rooted Android device (SuperSU)
- ANY tool to flash a ZIP (custom recovery or FlashFire app)
Installation:
1. Custom recovery - open file using "Install Zip" option and confirm "Yes - install..."
2. FlashFire - open file using "Flash ZIP or OTA" option (default mount options). Tap "FLASH"
How to check:
Just check if /data/initd_test.log file exists (optionally you can check its content)
Changelog:
v1.3:
★ This version automatically detects privileges of launched sh script used to trigger init.d and if these are not sufficient to remount /system rw - all commands are automatically expanded to "/su/bin/su -c [command]" or "/system/xbin/su -c [command]" (depending on SuperSU install mode)
★ Fixed problem with "exit 0" at the end of used sh script resulting that simply added new lines never worked. This version automatically detects such case and moves "exit 0" at the end of modified file
★ SELinux context autodetection - starting from v1.3 modified file has always exact same context as original file
★ BusyBox will not be used anymore, even if exists (checking the presence removed)
v1.2:
★ Starting from this version installer performs more secure and only 100% reversible actions. Original *.sh file is never touched (just renamed to *.bak to keep its original attributes, including context). Installer will try to set to modified file as many attributes taken from original file as possible (instead of forcing "known values").
★ Added initd_remover.zip. Use it if you want to remove Init.d support (enabled by script from this thread!) and restore 100% original system files
v1.1:
★ Avoids potential WiFi problems in case of Samsung S6 (and probably other Samsung's Exynos based devices running Android 6.0.1) - see post #3
v1.0:
★ Initial version

Strange as my installer in case of G920F should only add to /system/etc/init.sec.boot.sh following lines:
Code:
# Init.d support
mount -o rw,remount /system
chmod 777 /system/etc/init.d
chmod 777 /system/etc/init.d/*
mount -o ro,remount /system
busybox run-parts /system/etc/init.d
or following if busybox has not been installed:
Code:
# Init.d support
mount -o rw,remount /system
chmod 777 /system/etc/init.d
chmod 777 /system/etc/init.d/*
mount -o ro,remount /system
ls /system/etc/init.d/* 2>/dev/null | while read xfile ; do $xfile ; done
Original file should be renamed to /system/etc/init.sec.boot.sh.bak, so you can just delete modified init.sec.boot.sh and then rename init.sec.boot.sh.bak -> init.sec.boot.sh to revert changes (+ delete /system/etc/init.d folder but it's just a cosmetic)
...but before you do it - it would be great if you help in further development and try if following command put in terminal emulator or adb shell will help:
Code:
su
mount -o rw,remount /system
chmod 550 /system/etc/init.sec.boot.sh
chown 0:2000 /system/etc/init.sec.boot.sh
chcon u:object_r:sec-sh_exec:s0 /system/etc/init.sec.boot.sh
mount -o ro,remount /system
...then reboot device
EDIT:
Anyway - #1 has been updated as I found potential permissions / SELinux context mismatch in case of Samsung's Exynos based devices running Android 6.0.1. NOTE: It will not fix broken installation already done - you need to revert changes first (as I mentioned above - by deleting init.sec.boot.sh and renaming init.sec.boot.sh.bak -> init.sec.boot.sh) and then re-flash v1.1
Another update

Original *.sh file is never touched (just renamed to *.bak to keep its original attributes, including context). Installer will try to set to modified file as many attributes taken from original file as possible (instead of forcing "known values").
★ Added initd_remover.zip. Use it if you want to remove Init.d support (enabled by script from this thread!) and restore 100% original system files
@_alexndr , definitely mate will give a shot , later , thanks for ur work xD ,
good work bro will test more with new update
Good work ?
Sent from my A66A using XDA-Developers mobile app
Another update
Changelog:
v1.3:
★ This version automatically detects privileges of launched sh script used to trigger init.d and if these are not sufficient to remount /system rw - all commands are automatically expanded to "/su/bin/su -c [command]" or "/system/xbin/su -c [command]" (depending on SuperSU install mode)
★ Fixed problem with "exit 0" at the end of used sh script resulting that simply added new lines never worked. This version automatically detects such case and moves "exit 0" at the end of modified file
★ SELinux context autodetection - starting from v1.3 modified file has always exact same context as original file
★ BusyBox will not be used anymore, even if exists (checking the presence removed)
First of all really thank you for this script which works very well...except if included in the installation script.
The initd.sh is this
I use this command in the updater-script:
ui_print("@ Add init.d support");
package_extract_file("tools/initd.sh", "/tmp/initd.sh");
set_perm(0, 0, 0777, "/tmp/initd.sh");
run_program("/tmp/initd.sh");
delete("/tmp/initd.sh");
ui_print("--> Init.d Installed");
But not working. Got this error in recovery log
run_program: execv failed: No such file or directory
run_program: child exited with status 1
Any advice or a proper .sh script please ?
Thanks very much.

My script (as it is in post #1) is designed to be standalone installer. If you want to enable init.d by a sh script called from the updater-script - please try as follow:

Thanks for the answer. Will try it asap and give you feedback.

hello @_alexndr
So tried again with the sh modified script, but same thing. Same error and no initd installed unfortunately
If you have any other advice, i really thank you in advance.
i tried something different. I keep your original zip file, and put it in tools/initd folder in my custom rom
Then i added this in the updater script:
ui_print("@ Add init.d support");
package_extract_dir("tools/initd", "/tmp/initd");
run_program("/sbin/busybox", "unzip", "/tmp/initd/initd.any.stock.1.3.zip", "META-INF/com/google/android/*", "-d", "/tmp/initd");
run_program("/sbin/busybox", "sh", "/tmp/initd/META-INF/com/google/android/update-binary", "dummy", "1", "/tmp/initd/initd.any.stock.1.3.zip");
ui_print("--> Init.d Installed");
IT WORKS with this
Thanks
great job
You sir are an animal. This script is intelligently designed

Hey, Firstly thanks for all your work!
I've not tried this yet but I'm working on stock based ROM nd I want to enable to init.d support in it.
I've used the SuperR's Kitchen to enable the init.d support in the kernel nd I could find the script in the kernel too. Not sure if it'll work or not as I haven't tested in yet. So I hope you can tell me if I need to enable this way too or not,
Thanks.

Thanks a lot

Basically what I want to do is convert this into batch script for windows and by using Linux Binaries from Sourceforge create a script that basically does the same thing except it doesnt have to be pushed into my Phone's system it works directly in windows using ADB commands!
The script in question looks like this
Spoiler: THIS Script
Bash:

#adb push .\backupPartitions.sh /data/media/0/PartitionImages/backupPartitions.sh
#adb shell chmod 0755 /data/media/0/PartitionImages/backupPartitions.sh

I tried by guidelines from an "Appendix N. Converting DOS Batch Files to Shell Scripts" from another site to turn the shell script variables into batch script ones but since I got no experience with either of them my attempt turned into an amalgamation of the two's code in one..

additionally I have pretty much all linux commands's binaries on the same folder as the .bat script so as long as the syntax is correct and nothing finniky going on it should work technically but since I got no experience I can't do this on my own...
