It was 6.9.3 once I booted after the move. I assume it had been updated but waiting for a reboot to use the new kernel. Until I rebooted, it was probably still running on the 6.0.9 image.
If uptime and having the latest kernel ever becomes something I care about for this server, I might switch to Ubuntu Pro. It is free for personal use and it includes kernel livepatching. I can't imagine why I would need it for this use case though.
I am a control freak when it comes to my systems. I don't like them doing their thing on their own schedule. The network servers (Thinkpad Thinstation and a Raspberry Pi) controlling access, DNS, etc. are updated and rebooted regularly but in a staggered order so that my network is never down. One kicks off at 05:01 and the other at 05:31. Five in the morning is normally the time when I can't function, so it is the best time for a break. Not even my insomnia can withstand 5AM.
