I.e., after newfs(8) run, I can use the `c' partition of the DVD RAM media as I would use it on my hard drive. It was also my understanding that for DVD RAM, FreeBSD constructs a fake disklabel, on the fly, hence no need to write it to the media. > I've tried > # dump -f /dev/rcd0c /usr > but it tells me that I need 12 volumes.
