# androot
Chroot and systemd-nspawn rootfs installer

# Experimental
androot is experimental software and can lead to breakage! \
Only run these scripts with extensive knowledge of Linux (and Android if using Termux)!

# How to use
## Termux
### WARNING
If you want to use **androot** under Android you need a working Magisk or KernelSU installation. \
If you wish to install a (more limited) Linux distribution without root access use [Andronix](https://play.google.com/store/apps/details?id=studio.com.techriz.andronix) instead.
### Dependencies
- Magisk/KernelSU
- curl
- bash
- chroot
- bsdtar
- tsu
### Use
`curl -sSL "https://git.staropensource.de/StarOpenSource/androot/raw/branch/master/androot.sh"|sudo bash - --download`

## Linux
### Dependencies
- curl
- bash
- chroot/systemd-nspawn
- bsdtar
### Use
`curl -sSL "https://git.staropensource.de/StarOpenSource/androot/raw/branch/master/androot.sh"|sudo bash - --download`

# Distributions
- Arch Linux

# How does this work?
## tldr
We download & decompress a rootfs, apply some magic and make it useable with the help of `chroot` or `systemd-nspawn`.
## The short answer
1. check architecture
2. ask for target architecture, execution architecture(s) and distribution
3. download rootfs
4. decompress rootfs
5. mount rootfs
6. install updates and bootscript dependencies
7. apply patches (if using chroot)
8. download bootscripts
9. unmount rootfs
10. finish and print information about how to "boot" the rootfs
## The long answer
Just read the source code.

# How to test
`if shellcheck *.sh; then sudo env DIAG=true ./androot.sh --local; else echo ":: shellcheck failed, please resolve these errors"; fi`

# Annotations
```plain
### TOBECHANGED     -  this should be changed in the future
### UNIMPLEMENTED   -  not yet finished
### EXPERIMENTAL    -  experimental code, probably not safe yet
### MISIMPLEMENTED  -  implemented, but wrong
