Does a snapshot create a copy of all the files in memory? Just the files that changed? Or just the file blocks or contents (i.e. diffs) that have changed? So, would the snapshot have to be the same size as the cdrom or could it be smaller? Thanks, Sean ------------------------------------------------------------------------ Sean P.

The tools still don't support this, so you'll have to use dmsetup to create a writeable snapshot of the CD. Also be aware that you'll need to have a suitable fs on the CD, most CD filesystems are read only. - Joe _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
