I like it how updates are handled in GNOME. You can tick a box to install updates on shutdown. Then the system reboots, installs the updates during boot and directly shuts down the machine. Sounds like a robust way to handle it, once you got used to it.
@Lioh Just sudo pacman -Syu and hope that nothing breaks
@Lioh That's not specific to Gnome: https://pointieststick.com/2021/04/16/this-week-in-kde-offline-updates-are-now-optional/
And, yes, it's a great thing in general.
