To: hackers@freebsd.org Date: Thu, 3 Apr 1997 10:57:04 +0200 (MET DST) X-Mailer: ELM [version 2.4 PL23] Content-Type: text Sender: owner-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi, a curiosity. Assuming I want to backup a filesystem to a CD and don't want to bother with mkisofs (it is not only a matter of time, I often do not have the space for the additional cd image!) can I do the following: - unmount the partition - use the partition (/dev/wd0f or /dev/rwd0f ?) as the source for the CD data then in order to read the data I would only want to mount /dev/wcd0c as FFS instead of cd9660 -- any hope that it works ? And also, should I use the char or block device ? (just to save burning a couple of CD's in the trial&error process...)
