I'm pretty sure they *were* the only way. I don't think you
appreciate how much effort over the years in Samba has gone
into making sure people can't send paths that get resolved
out of the share definition. Symlinks really were a special
case as they can't be processed through any of the normal
path restriction code when being set.
