FlashDisk vs RamDisk+FlashDisk partitions

With a filesystem of that size using the read-only root approach is
defenitely the way to go.

I prefer to mount everything, except mount flash partitions as read-only
and change them to read-write for the short period when writing is really
necessary.

The current kernel is 2.2.17 with usb support among other things. I hope
to go to 2.2.18 with devfs and reiserfs soon (no promises on dates) and
perhaps add 2.4.x as experimental kernel sometime after that.

TTYL,
Adi
