Comment 4 for bug 1972982

Tested as much as I reasonably can on a Pi3 and a Pi4 running jammy server and jammy desktop releases. Didn't encounter anything that catastrophically broke things, but there were still a few minor cases where the previous version did nothing (because it was reading or writing the wrong file), but the new version did the wrong thing / broke things (e.g. keyboard settings were written, but ignored).

Ultimately though, I didn't manage to break boot / login with anything yet so I'd say this is "good enough" for now.
