-live\-boot will look for persistent and snapshot partitions or files labeled "live\-rw", "home\-rw", and files called "live\-sn*", "home\-sn*" and will try to, in order: mount as /cow the first, mount the second in /home, and just copy the contents of the latter in appropriate locations (snapshots). Snapshots will be tried to be updated on reboot/shutdown. Look at live\-snapshot(1) for more informations. If "nofiles" is specified, only filesystems with matching labels will be searched; no filesystems will be traversed looking for archives or image files. This results in shorter boot times.
