This is your annual reminder to do a snapshot (timeshift or whatever you prefer) before doing relatively minor changes to your system.
I was supposed to be in bed now, but instead I am stuck troubleshooting xorg refusing to start after an apt-get dist-upgrade.
And as far as friendly reminders go, I should’ve given myself an unfriendly reminder beforehand, as it’s not the first time…
UPDATE: Fuck nvidia 545. All my homies hate nvidia 545. 535 4 lyf!
Timeshift with BTRFS kicks ass. I have mine set for daily snapshots, retained for a week. Only the changes between snapshots are stored, so the extra disk usage is minimal, and easily justified by the peace of mind in case of fuck-ups or broken updates.
