I don't think that we have a different definition of hardlinks. I
wanted to point out that the 253 error problem becomes _really_
*obvious* and difficult when using hardlinks (pls. see my reply on
Kim's article for another example.) It isn't transparent, neither for
the user nor for a program, that he/it can't delete a file out of a
directory when it is open by another (or the same) process.

I don't think that hard links and the 253 error aren't related. It's a
matter of the concept. When allowing different paths for one file we
have to re-think what a directory entry is. At the moment a file and
its entry in the directory(ies) are connected in a very strong manner
(too strong in my opinion).

YEP, that's the point! The expire program can't delete a file entry out
of the directory comp/os/os9 when another user is reading an article
in comp/sys/m68k which is a crossposting, by accident.

Thank you for the hint! I will try to fix this. (At the moment I'm
happy to be able to post into the international news groups from my
machine in the office ...)

P.S.: I hope that I've expressed my opinion in a non-misunderstandable
(does this word exist?) way. Thank you for your patience ...

Yours,
