This makes sense for system services, but for user services it is a bit
strange that a user cannot modify its own preset files.

I'll be happy to provide a patch, but I must test the behavior of systemd
more carefully because user preset files in
       /etc/systemd/user-preset/*.preset
does not seem to work in systemd master [but maybe my testing was too
hasty, I'll keep you updated].

Thanks,
