Re: remount boot media with RW flag

[Axel <axel.ml@laposte.net>]

It works :
- full persistence on a hard drive partition (which hold a given label)
- cpio snapshot persistence on a second partition on the live media, 
with a restricted list of files due to /etc/live-snapshot.list 
configuration file. (at first boot the snapshot has to be created 
manually with live-snapshot, following reboots sync the snapshot file)

So it seems that mounting the live media as RW is not really required 
for the moment.
Both persistence media hold the files listed in /etc/live-snapshot.list 
though, but it s not a problem in my use case.

Thanks for yours answers.
