current working directory, actually. Which means you don't necessarily have
to use the filesystem root but only a proper start directory for these
mounts/links. But yeah, we don't know if said proprietary application 
does/doesn't cwd() to it. 

I suggest extending this mess a bit:

# mkdir -p /server/share
# mount.cifs ... 

and use UNC paths. '//server/share/dir/file.txt' will work out nicely :-)
