Yet another Musl-based lightweight container or distribution bootstrapper

musl_root

Yet another Musl-based lightweight container or distribution bootstrapper

Note: this is not completely done yet.

Features

• Prebuilt gcc toolchain
• libressl
• Essential to build GNU stuff (automake, autoconf, m4, make, awk, grep, sed, bison, flex)
• GNU coreutils

License

Build scripts are MIT
Patches have their license note in commit message (if not present, then given patch is MIT)

Special thanks

• @artizirk - for letting me to borrow his powerful AMD PC to finally build a toolchain

musl_root's Issues

Think about actual distribution name

But seriously, this needs more suitable name.

Build own musl toolchain

Replaces usage of toolchain from musl.cc introduced in commit a11627d, because given toolchain looks for libraries/headers in /$(uname -m)-linux-musl-native prefix.

Possible solution would be to configure toolchain to use system libraries/includes path, but as musl_root is compiling everything from source already, then it's better to build own toolchain.

curl is not linking to libressl

Related to: #1 - toolchain not using system include/libraries directories.

Script colors

Because... who doesn't like colors?

Of course make this option configurable using script arguments or config.sh

Package manager

Possible candidates:

• pacman
• xbps

Logging

Log everything to files out of box. It aids with debugging.

Also make colours appear on log files (See #3)

Stage 2

Honestly I am not sure if I should ever add stage 2 and what should it do exactly?

Make possible to build musl_root from musl_root

A distribution, which is capable to build itself. Sounds neat.

Idea came from https://github.com/pikhq/bootstrap-linux/

Missing /etc/passwd, group and shadow

makepkg requires non-root user to build packages, but to create accounts,
one needs to have /etc/passwd, group and shadow.

By default, those aren't provided

Solution: install libstdc++

Add fakeroot

Fakeroot doesn't seem to handle stat*() syscall at all (package from Alpine Linux works) Obviously if I test with busybox tar (busybox is statically linked) 😒

Work in progress patched fork is here

makepkg is unable to build packages using busybox utilities

Installing GNU Coreutils fixes it.

chroot fallback does not mount proc, sys or dev

Current solution is to make sure that bubblewrap (bwrap) is present on host system
