It's partition `c' (which is a magical alias for the entire disk/slice). /dev/vn0 is the buffered device denoting the entire vn0. If vn0 is not sliced, /dev/vn0c would be an alias for it. If vn0 is sliced (i.e., has an fdisk table), /dev/vn0c would be an alias for the first BSD slice found on it, while /dev/vn0 would still be the entire vn0 device. Don't forget that all these are buffered devices. Except for mounting, you probably do want to use raw devices (/dev/rvn0). -- 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. ;-)
