Re: Should hard links to directories work?

I don't have a use for it :-) - I only ask as I'm integrating the YAFFS
filesystem (see discussion elsewhere on these lists...) and thought of the
question while writing test cases.

FWIW, the only time I've ever come across directory hardlinks being useful
is in a chroot on a standard Unix system where it's sometimes a good idea to
nobble '..' (usually to be the same as '.') to preclude one of the standard
gaol-escape tricks.

Remember that eCos has no concept of users. Everything runs in the kernel -
everything is privileged, arguably higher than the 'root' user of the
standard Unix model.
