Yes and No, The problem is still there but when your dealing with an 8MB
FreeBSD system (m0n0wall) all's you have to do is make a ram drive and
copy the system to it. Then the only time you access the Flash device is
at boot or when making changes to the config file, etc, this is how
m0n0wall does it.
