Subject: Simplify chroot setup by dropping build_config.groups
X-Git-Tag: e2factory-2.3.15rc1~224
X-Git-Url: https://git.e2factory.org/?a=commitdiff_plain;h=813d16950d160bc742ce79ef20444b58f986e5ea;p=e2factory.git

Simplify chroot setup by dropping build_config.groups

Use chroot groups of the result instead of going through
build_config.groups. Make sure res.chroot is sorted independent of
proj/chroot.

Previously we did a complicated dance adding all required groups to a
build_config dict and then iterated over the entire chroot table. The
order in which chroot groups were untared did depend on the order of
appearance in proj/chroot.
