Actually I don't think that's true any more, most file systems on most Unixen
do not allow it. However it appears it's still the case for Solaris so it's
still a good point.
I'm sure it's not true for modern versions of Linux and I thought it was false
for other modern OSes -- I'm surprised it's not for Solaris even.
