These two fields allow to specify a different default assignee for ticket opened against
this package in bugzilla. Note: The EPEL field is
always displayed for packages in the 'rpms' namespace regardless of whether it
is used in bugzilla or not.
spec: Test for /var being writable before making /var/log/journal
rpm-ostree has `/var` be read-only during package installs, because
a whole part of the "transactional update" model is that your system's
data stays untouched, and `/var` is system data.
See e.g. https://src.fedoraproject.org/rpms/mock/pull-request/2
and the tracker https://bugzilla.redhat.com/show_bug.cgi?id=1352154
