Send a notifcation via notify-send
Add `systemctl --failed` to my shell startup script
Send myself emails
None of these are quite ideal. Notifications are disruptive of the current workflow and ephemeral, meaning I might forget about it if I don't deal with it immediately. Similarly, reading `systemctl --failed` on every new terminal is also disruptive but at least it makes me not forget about it. Both of these are also not really applicable to server systems. Sending myself emails feels a bit wrong but has so far been the best solution.
How are other people solving this? I did some research and I am surprised that there isn't a more rounded solution. I'd expect that pretty much every Linux user must run into this problem.
