Hmm.  I guess jakenet.img.gz is my initrd.  I just thought of initrd as
the thing you put drivers on and was only there until you loaded over
the real root fs.  The root fs is in the initrd.

The initrd was created like this:

#! /bin/bash
echo "----> creating blank disk image"
/bin/dd if=/dev/zero of=/spare/jakenet/jakenet.img count=32768 bs=1k 2>/dev/null
echo "----> formatting blank disk image"
/sbin/mke2fs -q -F /spare/jakenet/jakenet.img 2> /dev/null
echo "----> mounting disk image"
mount -o loop /spare/jakenet/jakenet.img /mnt/misc
echo "----> copying Jake distribution to disk image"
/bin/cp -a /spare/jakenet/jakenet_root/* /mnt/misc
echo "----> unmounting disk image"
umount /mnt/misc
echo "----> compressing disk image"
/bin/dd if=/spare/jakenet/jakenet.img bs=1k 2> /dev/null | /usr/bin/gzip -v9 > /spare/jakenet/jakenet.img.gz 2> /dev/null


I'm running kernel 2.2.20 and mknbi-1.2 if that makes any difference.
