I'm curious why the symlink is created at all... or in other words,
why systemd looks in /usr/share and ~/.local/share for user units in
the first place? It is neither documented in systemd.unit(5), nor
consistent with the system unit paths, nor makes much sense since
AFAIK the units are "configuration", not data?
