I tend to use systemd-nspawn containers for building rpms. So for
example, I have a Fedora 24 system and use its dnf to create e.g.
Centos 7 container root and then build Centos rpms from within that
container. If I understand the change correctly, this is going to
break since the Centos 7 rpm-build will not be able to read the
database created by the Fedora 24 dnf.
I know more people using dnf/rpm to "manage" the containers and this
is somewhat a regression for us. I'm not sure there is a way to
prevent this breakage... So just FYI. :)
won't regular mock chroot have the same problem?
