Add small bubblewrap like program as a build step #339

Open MaxHearnden opened 9 months ago

MaxHearnden commented 9 months ago

This allow the user to perform a rootless build without bubblewrap on machines with user namespaces enabled

I understand the idea/implementation in principle. Would you mind outlining any particular, specific usecases for this?

MaxHearnden commented 9 months ago

It's to reduce the binary seed required for an unprivileged build to just hex0+kaem-optional and can be used with the following commands

cp sysa/stage0-posix/src/* .
cp sysa/after_wrap.kaem after.kaem

# This stage could be integrated into after_wrap.kaem
echo "CHROOT=True
CHROOT_WRAP=True" >> sysa/bootstrap.cfg

./bootstrap-seeds/POSIX/x86/kaem-optional-seed

I like it but 2 minor details: 1) the syscalls should added to M2libc such that the code becomes more standard C. 2) the wrap.c program belongs in mescc-tools-extra which live-bootstrap does already use and will allow other bootstrapping projects to leverage your work.

great work

If this could be

rebased on master
updated to reflect that wrap.c is in mescc-tools-extra

I think I'm happy to include this in principle.

436 will bring in wrap.c into live-bootstrap, although currently unused
