Subject: Make sure the mount units pulled by 'RequiresMountsFor=' are loaded (if they exist)
X-Git-Tag: v228~225^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F1501%2Fhead;p=thirdparty%2Fsystemd.git

Make sure the mount units pulled by 'RequiresMountsFor=' are loaded (if they exist)

We should make sure that mount units involved by 'RequiresMountsFor='
directives are really loaded if not required by any others units so
that Requires= dependencies on the mount units are applied and thus
the mount unit dependencies are started.
