I would also look at the SMART data and run a test.
Have you tried building it?
What's in the log on the Windows side?
Does Linus still maintain that much control over it? I feel like I read something a few years ago about him starting to step back.
No, it's the same on the Windows side. Personally I like to build a new one in parallel, then migrate. I do plenty of upgrades on desktops, but I don't think I've ever done one on a server (except stuff like CentOS 7 to 8 where it's not really that significant of a change).
Migration is the safe option, but if it's a huge pain to migrate, I might do the in-place upgrade with a rollback plan ready if it really goes poorly.
I'm not familiar with how Avahi works, but I assume it uses broadcast packets. Do you actually have routing between two networks, or is it just a wireless bridge? Do broadcast packets transit the bridge? Have you taken a packet capture from both sides?
Aren't you supposed to add modules by putting them in some config file so they get added automatically?
Fixing your problem should also be achievable from single-user/rescue mode too, no need for a rescue disk.
I suppose you could put all the media on it by sneakernet and directly connect it to your TV.
USB easy transfer cables? Sure, looks like they just present a point to point network, so you can do whatever you want over that link.
With Ubuntu Pro. I'll stick with Alma, thanks.
Event log, probably application and security logs. I think there's a separate RDP log in the event viewer tree too, but I'm not sure if it's used.
