Because the `c' partition always covers the entire FreeBSD slice, and is relative to the beginning of the slice.

Everything except su# is meaningless, should you insist on still using disktab at all. Some of the meaningless entries (ns# nt# nc#) are required though. You can invent silly numbers for them if you've got a su# entry. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
