Yeah I really liked the s4 mini. It was a great form factor. It is a little slow these days but still works ok, I think I've got Lineage 17 built for it. I can still get batteries on Amazon for it? But the networks banned it so it's just a media device now.
Yes, can be an issue. But if you set it up right, use dkim/dmarc/SPF, and don't do stupid things like spam people, you're good. It isnt hard. It is just hard getting a static IP for a homelab, really.
Opensuse Tumbleweed. You get the drivers, it's stable, and the one time it isn't you just roll back to the prior snapshot in the boot menu that it takes automatically. Steam runs great on it. Honestly about the best there is.
Yeah I don't know either. I had a problem once or twice with it because I powered it off randomly when it locked up under load (did this a lot, this machine is 12 years old and needs maintenance). Btrfs check repair fixed it. Snapper rollback is awesome for updates. Under opensuse at least it seems extremely stable.
I got some doordasher with a typoed email who is apparently constantly driving under the influence for doordash because I keep getting reminders that that's against Doordash policy
A galaxy tab 6 with lineage is awesome, if you can score one that is unlockable. Their stock software is not great.
