<DIV><SPAN class=671155022-03062007><FONT face=Arial color=#0000ff size=2>There
are basically two ways in doing it</FONT></SPAN></DIV>
<DIV><SPAN class=671155022-03062007><FONT face=Arial color=#0000ff size=2>One is
to create a binary "blob" where each part (kernel and fs) is placed
at a certain location and the space between them is padded</FONT></SPAN></DIV>
<DIV><SPAN class=671155022-03062007><FONT face=Arial color=#0000ff size=2>These
location should match exactly the kernel mtd partition settings in terms of
size.</FONT></SPAN></DIV>
<DIV><SPAN class=671155022-03062007><FONT face=Arial color=#0000ff
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=671155022-03062007><FONT face=Arial color=#0000ff size=2>The
other method i have used, uses some "magic bytes" at the end of a jffs2
filesystem to mark it</FONT></SPAN></DIV>
<DIV><SPAN class=671155022-03062007><FONT face=Arial color=#0000ff size=2>Then
kernel and the fs are joint and a kernel patch is used to find where the
filesystem starts/ends</FONT></SPAN></DIV>
<DIV><SPAN class=671155022-03062007><FONT face=Arial color=#0000ff size=2>This
is the method used by Openwrt (in the kamikaze
version)</FONT></SPAN></DIV></DIV>
