Bug#789610: symlink(2) refuses to let me create an empty symlink

[Ian Jackson <ijackson@chiark.greenend.org.uk>]

Package: linux-image-3.2.0-4-amd64
Version: 3.2.68-1+deb7u1

I may be tilting at windmills here, but I think
   ln -s '' foo
should work, rather than failing with ENOENT.

The fact that it didn't work inconvenienced me while I was trying to
write a test case for some other software.  I would have been happy
for the link to be created and then be un-dereferenceable.

I would, in fact, have been happy with either the traditional BSD
behaviour (create the link, treat it as a link to "."), or the
traditional SysV behaviour (create the link, dereferencing gives
ENOENT).

Do you think you could try to use any good connections you have to get
this fixed ?
