Using x or X does unfortunately not work correctly to prevent D entries
from happening. See
http://cgit.freedesktop.org/systemd/systemd/tree/src/tmpfiles/tmpfiles.c?id=5d31974e44b8fa163f859d8467a3667ed52056d0#n859
(there’s a FIXME in the code)

I think we should split up tmp.conf into one entry per file, so that we
can override/nullify the entries by creating a file/linking to
/dev/null.

If you agree I can start working on a patch for that.

Also, I noticed that integer values for TMPTIME are not migrated,
e.g. TMPTIME=5 will not be properly migrated. Is that intentional?
