[Voyage-linux] Shorewall Read Only /var/lib/shorewall/ problem

[Kim-man 'Punky' Tse]

Hi all,

There was some discussion.  I was now thinking to use unionfs/aufs to 
hold all modified files to a copy-on-write (/cow) directory, then have a 
manally script that sync cow back to flash disk.  Is it possible and are 
there any recipe for this?

Regards,
Punky
