Clue:

root:x:0:1:Super-User:/:/sbin/sh
                        ^^^^^^^^

So you won't have the problem of being without a shell if you can't mount user.
/sbin isn't not a symlink.  It's part of root.  And further, /sbin/sh isn't
dynamically linked:

[fenris:/sbin:7]$ file sh
sh:             ELF 32-bit MSB executable SPARC Version 1, statically linked,
stripped


However, you're right.  Without /usr, you don't have fsck, mount, or format,
and you can't just copy them over to /sbin because they're dynamically linked,
which leaves you a single option: boot from CDROM to fix stuff:


[fenris:/sbin:9]$ file `which fsck`
/usr/sbin/fsck: ELF 32-bit MSB executable SPARC Version 1, dynamically linked,
stripped
[fenris:/sbin:10]$ file `which format`
/usr/sbin/format:       ELF 32-bit MSB executable SPARC Version 1, dynamically
linked, stripped
[fenris:/sbin:12]$ file `which newfs`
/usr/sbin/newfs:        ELF 32-bit MSB executable SPARC Version 1, dynamically
linked, stripped

So you know what, fuck it, and just set it to /usr/local/bin/bash and don't
worry, because like Lion said, you won't be doing very much anyway. :)
