The old Dockerfile and Makefile pair didn't meet the requirements of the
ci-test. Namely, the (very sensible )requirement of not shipping a
private key was missing, the sysusers hook wasn't executed properly and
the /var/cache/pacman/pkg folder was remoed (and it's specified in the
pacman MTREE package)
This commit adds:
- Systemd sysusers hook is ran on the dockerfile
- The dockerfile also populates the archlinux keyring
- Remove the libalpm hooks as they are uneccessary now
- Moved the package cleanup before the tar step on the makefile
The old makefile required commands to be run as a superuser, which
may become problematic when deploying on the archlinux infrastructure.
Use fakeroot and regular pacman commands to allow for to bootstrap a
rootfs.
