[Voyage-linux] How does this /ro /rw thing work?

[Daniel Musketa]

Hello,

looking for a small distro for a firewall and traffic shaper I found voyage 
and installed it (0.2-stable) on a 128 MB CF card.

It's running fine for 8 days now but I'm a liitle worried about `df`. Space 
on /rw is getting short because of big logfiles (for debugging the fresh 
setup).

How is this whole /rw /ro thing working? 

/dev/hda1 (the CF card) is listed in /etc/fstab as to be mounted as / but 
doesn't appear in the output of `mount`. There's an rw rootfs AND an 
ro /dev/root mounted on /. Can someone explain please?

When I run `remountro` (which actually does `mount -o remount,ro /`) is 
writing to CF card really disabled totally?

Where ans how is the data from /rw written to when I shut down?

Can I increase /rw's size somewhere?

Where can I add feature requests? On the wiki page?


Regards
Daniel
