Kernel upgrades are done except for four machines, one of them is just borked, somehow the image got corrupted so it’s being restored from backups.  Could not get the drivers for the Fusion I/O drive to compile under 5.16 so I’ve ordered a more main brand conventional SSD, it won’t provide quite the I/O rate but it still should be adequate.  So the main physical server is still on 5.13.19 for now.  UUCP also won’t work with a modern kernel, issue with Centos’s start up routines wanting a feature that was deprecated.  Zorin is bored.  And Manjaro had to be restored from backups but hasn’t been brought totally current with upgrades yet as I am having some issues with the AUR processing.
