Hello all,
it seems I missed something but...
If I enter the /n directory, I can make 'cd' command into non-existent
(not mounted) 'directory' (or filesystem) successfully.
% cd /n
% ls
9
9fat
...
% cd blahblah
% pwd
/n/blahblah
Can you explain me, why it happens?
Thanks in advance.
Pavel

Thanks a lot.

What is it good for?

9fs, for example.
i can do '9fs arbitrary-machine', and not have to worry about whether
/n/arbitrary-machine has been created ahead of time or now. that's the
most common use. without it, you'd have to create mount points in
advance of knowing what sets of things you'd want to mount.
it has downsides, like your "phantom cd", which is why it's only used
where it makes sense.

I find it kind of ironic that Anthony is replying to a "missing
directory" question. Please check the requests on the list that i
could not satisfy and put together the pieces.
your humble servant.

Alternatively, if '9fs' would 'mkdir' automatically, the sequence
would be:
- 9fs (automatic 'mkdir' and 'mount')
- ...usage...
- user 'unmounts' the fs...
- ...and the directory is still present... :-(
Clear, thanks for explanation.

actually, the more likely result would be "permission denied".
you'd need to mount ramfs on /n to do it this way.

Correct. Please ... no speculative posts - blokes. Test it first. If
that isn't obvious please go to slashdot and contribute to the open
sewer, the consensus of the ill-informed.
