I'm talking about the "compatibility slice" or whatever.
E.g., on my machine:

/dev/sd0s2b                     none            swap    sw 0 0
/dev/sd0a                       /               ufs     rw 1 1
/dev/sd0s2e                     /usr            ufs     rw 1 2
/dev/sd0s2f                     /var            ufs     rw 1 2
proc                            /proc           procfs  rw 0 0

Isn't /dev/sd0a really /dev/sd0s1a here? That is, sd0 has a normal
partition table.
