persistent mode clarification

[fboudra at gmail.com (Fathi Boudra)]

hi,

for the record, until we have something on wiki.debian.org.

i try to use the persistent mode, with an alternative to the dedicated
partitions way.

from live-initramfs manpage:
[...]
        persistent
           live-initramfs 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.
[...]

someone know how the files labeled "live-rw" "home-rw" way works ?

cheers,

Fathi
