Thanks for your reply Gene. I have looked at your rosh but I'd like to
make it rwosh. ;-)

One thing I'd like to do is, say, from syslinux download a new kernel image
over TFTP and then write it to the filesystem. Or do some other sort
similar FS writes. I certainly don't expect this to be needed by too
many people,
but I'd certainly release any changes I make which allow FS write support.
Basically, what I'm looking for is any words of advice on just where to begin
to add support. It may be a futile effort, but I'd like to give it a go. ;-)

Cheers and thanks again!
