This stuff gets better when SLICE comes into the picture, and you can disklable it, put an MBR inside each of the partitions, then disklabel the slices inside those, etc. 8) > > And why on earth do you want to swap on a ccd?

The CCDF_SWAP flag is somewhat ambiguous though, yes. The real issue is that dev/ccd/ccd.c:ccdsize() returns -1 for partitions that do not have type == FS_SWAP, so you can't swap on something that's not marked as a swap partition, and that includes the 'c' partition in the case where there is no disklabel on the volume. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
