Hi Jeff, "has anyone got a working deployment for ubuntu 20 or 22 or has everyone essentially given up on that for the time being?"
There are a couple of issues on Github where potential solutions have been discussed but making xCAT provision Ubuntu 20 or 22 is hacky at best and is unsupported in xCAT as it currently stands. There was an encouraging discussion on https://github.com/xcat2/xcat-core/issues/6681 and some of the recommendations in that could work but I personally haven't had the time to be able to run through it. RHEL/Rocky/Alma operating systems are our focus in the short term, and these will carry the highest level of support and workability in xCAT. "Will I save myself a lot of trouble if we just go with CentOS 8 or 9?" Outside RHEL, Rocky and Alma 8/9 carry the most support and, as of the next release, will have the disk image info included in xCAT to make them easier to work with. CentOS Stream hasn't really been adopted within the xCAT project and in theory it should work but I'd recommend using Rocky or Alma if you do not have a specific need for something in CentOS Stream.
