The kernel upgrades went mostly smooth except for the client mail server.  Had issues with systemd timing out before it mounted all the disk partitions.  This is a virtual machine configured to use a physical partition on a RAID10 device on this host computer and using virtio disk.  This has not been a problem in the past but did not want to work today.  Changing the disk emulation to SATA made it work so apparently there is some ugliness with the virtio devices in the newest kernel although it was not a problem with any of the virtual machines that used a file rather than a partition for their virtual disk.

     At this point the virtual private servers and host computer is now running 5.12.2, this because 5.10.x has not been stable on that machine.  The rest are running 5.10.35.

     https://friendica.eskimo.com/, https://hubzilla.eskimo.com/, https://nextcloud.eskimo.com/ and all other Eskimo North services are back online and operational.  With the exception of client mail access pretty much everything else was online by 11:30PM, but it took slightly longer than that to bring the mail server back online.
