The problem seems to be that hard links are useful to conserve disk
space. Well how about implementing copy-on-write semantics in the file
system? That is, cp foo bar should not duplicate any file data, but
only a little metadata. That should be transparent to user programs,
but it would have the distinct advantage that everyone knows the
semantics of cp, while it seems people are getting pretty confused
about ln.

I think the rest of ln's uses are being done by file owners.
Counterexamples welcome.
