True. A symlink cannot traverse 'up' the chroot; only a hardlink can (to a
file). Personally, I would not use something as beta as "mount_null". When
the man pages say: "(READ: IT DOESN'T WORK)", I would stay clear of it.

There are other ways, though. You say your chroot is at:

 /etc/ftpchroot

I'm not necessarily sure whether the root-partition is the best place for a
chroot; but working from that fact, you could "reverse" the condition.
Instead of trying to link to /ftp/share, from within the chroot, you could
do the opposite: first create the following directory:

    /etc/ftpchroot/ftp/share

Then, in /ftp/, symlink to within the chrooted dir:

    share -> /etc/ftpchroot/ftp/share

Then "/ftp/share" is accessible from both the 'real' and the chrooted
environment, pointing to the same directory.
