# While both runc and crun are needed in the support of different distros
# and environments, packaging will need to instal one and suggesting the other.
# This can cause some ambiguity for automation, where more concrete, predictable
# behavior is desirable.  Instead of fighting with or complicating the packaging
# itself, workaround the problem.  Always removing 'runc' in Fedora since it's
# exclusively cgroupsv2 focused as of release 31.  However, ensure the runc
# is downloaded to $PACKAGE_DOWNLOAD_DIR for the minority of use-cases where
# automation needs to swap it in.

# On 2020-07-23 we needed this code to upgrade crun on f31, a build
# that is not yet in stable. Since CI:IMG PRs are a two-step process,
# the key part is that we UN-COMMENT-THIS-OUT during the first step,
# then re-comment it on the second (once we have the built images).
# That way this will be dead code in future CI:IMG PRs but will
# serve as an example for anyone in a similar future situation.
