SystemD now knows my path on user login, which is a great help as
Emacs has always been kinda weird in server mode (which I've only just
figured out to be a problem of SystemD rather than Emacs).
debuginfod's profile script for some reason doesn't work for zsh,
which means the ~DEBUGINFOD_URL~ variable isn't set. So set it up
here.
(Shell)~propagate change to emacs service (no -s MAIN) and editing
(XServer)~state explicit full path for lock script for ease of
understanding (it's a user script, not some other program)
By reinstalling arch on my laptop, I've had the chance to see any
loose ends or errors in my setup that, by virtue of how fresh the
system is, I'm motivated to fix.
