FreeBSD's exports implementation will only allow you to associate
mount options per local filesystem per remote machine, so this
version:
> /usr/home pc02 pc02
> /cond1 -mapall=user2 pc01 pc02
> /cond2 -mapall=user1 pc01 pc02
is correct, but only if /cond1 and /cond2 are different filesystems.
If they're the same, this won't work.
Maybe you do something clever with exporting nullfs versions
of them and adding those to exports, but I haven't tried that.
