Create a fourth partition to put the raw kernel image in.

Create a fourth partition to put the raw kernel image in.

This is a short term fix for machines that can't boot a kernel from
the root file system of an SDCard.

This issue depends on issue 602027.

Some comments on kernel_fetcher.sh.

Overall, why not just change build_image.sh to put a copy of the kernel into the
output directory rather than pulling it out of the rootfs?

http://codereview.chromium.org/600074/diff/1/3
File src/scripts/kernel_fetcher.sh (right):

http://codereview.chromium.org/600074/diff/1/3#newcode37
src/scripts/kernel_fetcher.sh:37: sudo losetup -d "$LOOP_DEV"
Maybe this should try to umount "$[LOOP_DEV}" first?

http://codereview.chromium.org/600074/diff/1/3#newcode55
src/scripts/kernel_fetcher.sh:55: mkdir /tmp/kernel_fetch.$$
You should remove this directory after you are done with it.

Comments addressed.  You're right that we should put the kernel in the build
image output.  But let's wait on that until we have GPT support.  Then all of
this will change.  This just get's us going.

http://codereview.chromium.org/600074/diff/1/3#newcode37
src/scripts/kernel_fetcher.sh:37: sudo losetup -d "$LOOP_DEV"
Done

http://codereview.chromium.org/600074/diff/1/3#newcode55
src/scripts/kernel_fetcher.sh:55: mkdir /tmp/kernel_fetch.$$
And Done.

LGTM

I agree to get this in for now. Thanks!
