factory_shim: Change the size of ram disk The 400M ram disk is not enough when installing. This CL should be a temporary solution.

Build logic for creating standalone initramfs environments.
See the README files in the respective subdirs for more details.
Normally you wouldn't build in this directory directly. Instead, you would build the chromeos-initramfs package with the right USE flags. e.g.:
$ USE=recovery_ramfs emerge-$BOARD chromeos-initramfs
That will install the cpio initramfs files into the sysroot for you to build into a kernel directly. The various build scripts would then be used to make the right kernel/image using those (e.g. mod_image_for_recovery.sh).
You could build these by hand for quick testing. Inside the chroot:
$ make SYSROOT=/build/$BOARD BOARD=$BOARD <target>
That will create the cpio archives for you.
It is possible to debug few of the initramfs targets in QEMU. Read test/README.md for more information.
Also, here is a shortcut for developing/debugging graphical bits in initramfs, without having to create a full image for every iteration.
After emerge-$BOARD
, find your initramfs package from chroot /build/$BOARD/var/lib/initramfs
and copy to a running DUT, for example /tmp/recovery_ramfs.cpio.xz
, then do followings on DUT:
mount -o remount,exec /mnt/stateful_partition
mkdir /mnt/stateful_partition/test; cd /mnt/stateful_partition/test
xzcat /tmp/XXXXXX_ramfs.cpio.xz | cpio -iv
stop ui; kill $(pidof frecon)
bind mount /dev, /proc, /sys and /tmp in /mnt/stateful_partition/test
chroot /mnt/stateful_partition/test/init
