Previously:
We used images built from pre-mass-rebuild composes but installed packages
from post-mass-rebuild composes. This caused weird stuff like sshd crashing
when installing non-related packages via dnf.
Now:
Both the image and repositories are post-mass-rebuild ones. This should solve
these weird issues.
