Several issues running "mirror-registry" depending on root/rootless and configured variables.

mirror-registry version v1.3.4 / RHEL version 9.1 (up-to-date)

Installing with the following variables works but IPv4 listening only.
quayHostname="rhel9-bastion.lab.local"
quayRoot="/home/vince/mirror/ocp4"
quayStorage="/home/vince/mirror/ocp4"
pgStorage="/home/vince/mirror/ocp4"
initPassword="password"
sudo ./mirror-registry install --quayHostname $quayHostname {color}
--quayRoot $quayRoot --quayStorage $quayStorage {color}
--pgStorage $pgStorage --initPassword $initPassword

I noticed if I don't sudo "mirror-registry install" command above. I will see port 8443 bind to IPv6 but not IPv4. But running without sudo causes other issues. The install fails at "Enable lingering for systemd user process"
