Systemd precheck cachefile parse problem

Hi!

I dont know where to report this as ... I am running debian but this
likely affects others.
So i give you problem and solution here, please tell me if i should file
a bugreport elsewhere..

on an upgraded debian system the openafs-client does not start because
the system precheck file complains that the mountpoint is not a directory.

In my case the file was used previously and has comments inside (for
automated install multi-use)

So i included that the check  is only run on no-comment lines (patch
included).

One might extend this to let awk check that the layout of non-comment
lines is indeed
dir:dir:reasonableSize
or similar.

i hope that this helps some people as i found several complains in
multiple places and a fix coming from upstream is welcome...

Thanks a lot for your work (and welcoming any dual-license openafs!)

Here is the patch that works for me:
