This seems to trigger some strange behavior in the systemd.bbclass which
adds 'Conflicts' (and 'Also') to the FILES list.  E.g. after this, the
'shutdown.target' file is moved into the 'systemd-binfmt' package.  This
in turn causes 'systemd-binfmt' becoming a rdependency of 'systemd' due
to dead symlinks.

I would avoid the 'inherit systemd' in the systemd recipe and package
the files and .target.wants/ symlinks as-is in ${systemd_unitdir}.
