To satisfy this in the near term as we sort out a more appropriate
long term solution, we now have F22 + Upddates nightly ISO builds
as well as re-enabled vagrant and qcow builds.
For anyone interested in the "secret sauce" here:
- the ISOs are built in a mock chroot with this script:
- vagrant/qcow images were re-enabled in the releng script here:
Once we have pungi4 in shape and/or the run-root koji plugin live in
production, we will likely be able to move these sort of tasks into a
more well defined process better suited for the long term but my hope
is that we'll no longer block the projectatomic team.
