Hi,

many thanks for clearing this up for me.

I had imagined this alright, but my initial investigation seemed to
contradict it.  It seems I was confusing myself.

It turns out that Samba displays junction points in a slightly odd way that
if you create a file in the junction point directory, you can list that
file in the location, but if you do a directory listing (on the junction
point), you find it's empty and has appeared in the other location.  If you
do a unix find for the file, you'll only see it once.

I'll probably ignore them to keep the output clean -- overly verbose output
like this causes people to ignore it entirely.

Would it be possible for Bacula to give a more precise answer?  The
message:
        "xxxxx.... is a different filesystem"

isn't always true.  In this case, we're talking about a symlink (of sorts)
to the same filesystem.  From your explanation it seems it can be either,
so it might be clearer if bacula could either used a less specific warning
or checked which and warned accordingly.

I can report this as a bug if that makes sense?
