FS: hardlinks on directories

[Stephan von Krawczynski <skraw@ithnet.com>]

Hello all,

although it is very likely I am entering (again :-) an ancient discussion I
would like to ask why hardlinks on directories are not allowed/no supported fs
action these days. I can't think of a good reason for this, but can think of
many good reasons why one would like to have such a function, amongst those:

- restructuring of the fs to meet different sorting criterias (kind of a
database view onto the fs)
- relinking of the fs for export to other hosts via nfs or the like (enhanced
security through artificially constructed, exported trees)

Would a feature like that be seen as "big action" or rather small enhancement
to the fs-layer?
Are there any supporters for this feature out there?

Regards,
Stephan
