Well, it's slightly nicer to use relative symlinks for things like this,
since this means that if you install an OS hierarchy into some
subdirectory somewhere the symlinks will always point to files inside of
the hierarchy, and not into the host's OS hierarchy, if you follow what
I mean.

I figure we should fix tmpfiles to understand that relative and absolute
symlinks are both OK, even though it should probably create only
relative symlinks.
