Great, with this a clone of the default branch (dist-vz7-u12) of
fedora-30-x86_64-ez results in an rpm that allows creating a bootable
fedora-30 container. It is only lacking the network-scripts package, so
networking does not start automatically at boot time before bringing up
the new container's interface manually and installing the rpm. I expect
this should be easily fixable by adding "network-scripts" to the
"os_packages" source.
The fedora-32-x86_64-ez dist-vz7-u15 source seems to contain a problem.
Container creation fails, because the cache creation step fails for "repo
'base2'". Running vzpkg create cache we get:
# vzpkg create cache fedora-32-x86_64
Creating OS template cache for fedora-32-x86_64 template
