Alpine chroot jail on Android
But why?
You might ask what’s the point of this because Termux exists? Right?
Well the answer is simple…
- Why thfq not??? Show your {boy,girl}friend that you’re a real boomer.
- Termux is for skids with questionable skills and
nationalities. :-D - You also get full software and hardware control.
- Way more efficient and extensible.
Step #1 Root your device
Blah blah blah.
Seriously this ain’t a guide for this.
But if you’re really this green you can find some information in these great forums:
- XDA Developers — Probably the most famous international Android forum.
- 4PDA — Really nice forum that has all sorts of weird stuff. (sadly it’s in Russian but pretty easy to translate anyway).
Step #2 Clone the Git repository
git clone 'https://gitlab.com/stnby/alpinedroid.git'
cd alpinedroid
Step #3 Connect your phone over ADB
$ adb connect 10.0.1.2
connected to 10.0.1.2:5555
Click Allow button.
"Allow USB debugging" prompt
Step #4 Move over and execute the setup script
Transfer the setup.sh script.
$ adb push setup.sh /sdcard
setup.sh: 1 file pushed, 0 skipped. 0.1 MB/s (1310 bytes in 0.019s)
Execute the transferred script as root.
$ adb shell su -c 'sh /sdcard/setup.sh'
> prepare
