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!
Neat little guide (Arch, systemd) to set up automatic snapshots when you run a pacman/yay update and the option to chose snapshots in grub during startup. Really useful.
