   So a couple weeks ago I used a systemd feature… I am now being given reason to regret it severely

     So there's this thing called systemd-sysext. It allows you to put "overlays" on your filesystem that cause additional files to appear alongside the regular ones, intermeshed with the regular file hierarchy. I was super happy when I learned about this! That is a neat and useful feature!

     What I did not know is the moment you engage it, any "meshed" top-level directories are set readonly. So the sysext I installed put files in /usr/bin. This made /usr readonly. I did not notice this for two weeks.

     Let me tell you! When /usr is readonly! It makes GUI-mode ubuntu pretty confused !!!

     @mhoye Well, for example, one might run the GUI software updater app, or the GUI firmware updater app.

     @faassen Let me tell you, given how perpetually irritated I am at systemd haters, it's gonna be really frustrating if I myself turn out to hate systemd

     Shall I simulate being one of those systemd haters for you? Shouldn't be necessary as I am sure they are showing up
