Dropping caches (writing back all dirty pages to disk and clearing all the caches) is not necessary for factory tests. It can reduce the latency significantly. The scale is about 27s -> 3s, for running 2 empty tests.

This adds some '/dev/sdb' options to the grub2 menu, so that we can keep the
default boot partition /dev/sda3 while still using the USB key as a recovery
image. This is work in progress for EFI BIOS development.

This is useful for various JTAG and fastboot based flashing of
targets. It is also useful in that we will now have access to
USB card readers and mass storage devices inside the chroot.

TEST=Enter and exit the chroot cleanly.

Undoes a change from 5c3b457f. Hardcoding "--yes" in the
call to mod_image_for_test.sh instead of inheriting
image_to_usb.sh's "yes" was intentional. The user may not
pass --yes to image_to_usb.sh since they want to confirm
that they're writing to the correct device, but they already
told us that they want the image to be modified for test
with --test_image, so there's no reason to ask about it
again.
BUG=none

Migrate only issues that are open or that are already in the
spreadsheet. This way, the spreadsheet doesn't get cluttered w/ closed

After discussing with drewry, we can't come up with a better way to inject these root certs. We considered putting them on the stateful partition, but that opens up an avenue of attack (if you can get a root cert into the magic directory, then you can MITM login). Thus, we put it on the rootfs instead. The script that sets up the hashes for vboot will verify that this directory is not present in production images. That work is tracked here: http://code.google.com/p/chromium-os/issues/detail?id=2693

Add feature to mod_image_for_test to patch rootfs.
Change initctl path to get network but no chrome.
./image_to_usb.sh --install_mfg --install_autotest --test_image
which calls ./mod_image_for_test.sh --manuf

As with build_packages, only retries by default if you passed --jobs
even though build_image will indeed spuriously fail with only one job.
sync_build_test now uses jobs=#cores by default for both package and
image building. Eventually will also use this for gclient sync'ing
once that is better vetted.

now we could install to mmcblk0.
for vogue, we even change the uboot environment.
on Samsung, you had to use 'chromeos-install --skip_src_removable' because mmcblk1 is not removable somehow.

The safe_unmount function first tries a regular unmount, If that
fails it warns and tries a lazy unmount. If the lazy unmount fails
it dies.
Both unmounts take the -d option in case the mount is a loop device.

and "cat" stuff and pipe it to something that can write to a
file as root. For example:
echo "foo" | sudo_append /tmp/bar
will append "foo" to the file /tmp/bar as root. While
echo "foo" | sudo_clobber /tmp/bar
will truncate /tmp/bar and then write "foo" to the file.

sosa@'s statefuldev change, which installs all developer packages on
the stateful partition and has put /var there as well, means that we
can no longer just mount the rootfs on a usb stick and emerge packages
onto/off of the removeable device. We now need to mount the stateful
partition as well, and also bindmount from /var on the rootfs to /var
on the stateful partition. All portage state is stored there, among
other things.

The old format was: gzip(root filesystem). The new format is:
gzip(kernel parition length + kernel partition + root filesystem). The
length is 8 bytes (uint64 big endian).
This CL fixes the updater and the update generator to support the new
format.

This fixes the loop device leak. The problem is that inside the chroot, we
have /etc/mtab as a symlink to /proc/mounts. That works most of the time,
but if you mount something using "-o loop", it isn't cleaned up correctly
when you umount it. To avoid that, we either have to replace the /etc/mtab
symlink with an empty file when we create the chroot, or we have to make
sure that we never execute a "mount -o loop" command from within the chroot.
If we use an empty /etc/mtab file, the builds work fine, but then we can't
see any mounted partitions that the host creates outside the chroot (such as
USB keys), which causes other problems. Bleah.

Change build_image to support building a factory install image. Also,
a shell script and startup script to run the factory installer.
Change software_update startup script to detect if it's a factory
install and abort if so.
