jffs2 and Doc 2000

[eylon eyal]

hello
1) i saw the thread about recommended fs to Doc.
and i was wonderring if any one has a link to a good howto/tutorial how to 
create a bootable Doc with jffs2 on it? like the excellent tutorial about 
grub and DoC

2) alot of guys asks about ext2 and Doc... if ext2 is so bad so why is the big 
intrest in it? am i missing something about it?

3) anyone used jffs2 with DoC.?

thanks alot
