I've CC'ed the devel list as they might have already written a script
to do this...
I'm trying to create a USB install image like diskboot.img from and
for FC4. The thing is, I have to replace the default kernel with a
new tree to accommodate a new RAID card and Ethernet card which isn't
supported by the standard default kernel. I've got my upgrade drivers
in - no problems there; the kernel boots and finds the newer cards w/o
problem. The problem seems to be with updating the diskboot.img...
I'm using a FC4-updated kernel image (2.6.12-1.1447_FC4smp).
I've created the script below to help, but I can't figure-out why the
new kernel or the installer can't find my Ethernet card... Any tips
or suggestions on how to debug this would be great.
BTW> I'm planning to write this into a how-to once I finish for
everyone to follow as it's quite an involved process.
