@vermaden I ignored the political layer on purpose. I just had a couple of wines and wanted to see "what happens if I..." and then frankensteined a RHEL that boots with rEFInd on a ZFS root.. And (after patching serious parts of convert2rhel, removing sanity check functions), it did work and boot I still wouldn't trust my actual data to that system and my personal infrastructure runs ons FreeBSD (Server) and OpenBSD (Firewalls)
