[Libguestfs] [p2v PATCH 4/4] make-disk: inject EPEL9 repo in RHEL9 disk image

[Laszlo Ersek]

In RHEL9, "metacity" was replaced with "gnome-kiosk":

  https://bugzilla.redhat.com/show_bug.cgi?id=1951145#c4
  https://bugzilla.redhat.com/show_bug.cgi?id=1956984#c1

gnome-kiosk has particular requirements for the main application:

  https://bugzilla.redhat.com/show_bug.cgi?id=1999060#c13

We don't know if that's compatible with our separately opened XTerm
window(s). For now, let's stick with metacity, by pulling in EPEL9. We can
work on RHEL9 purity (including gnome-kiosk fixes and/or compatibility)
once a "standard" RHEL9-based image builder service becomes a realistic
prospect.
