In BSD systems a symlink's permissions do not restrict
anything.  They exist, and can be changed, and you can look
at them with ls -l, but they have no effect on what you can
do with the symlink.

I do recall an alternative implementation where you could
not use readlink without read permission to the symlink,
and you could not follow the symlink with search (x)
permission.  But I don't remember which one that was;
perhaps it was just experimental.

In NTFS symbolic permissions have a different interpretation,
which I don't know much about and may not be relevant here.
