These are just cluttering things and adding an element of "how does this
work?" because base_image_util was defaulting to the "usb" layout in
some places and "base" in others.
This change removes /usr/sbin/write_gpt.sh from images which we have no
use for. This allows us to drop the indirection of writing partition
tables by first writing out a script to call. Now cgpt.py can call cgpt
directly to initialize the partition layout. This opens the way for
further improvements to how disk images are created.
Enable sparse files for all dd and cp commands and replace some dd
commands that are really better off being truncate commands.
While in the neighborhood there were a number of useless sudo commands
for things that just happen to be in sbin. Call them directly instead.
Make use of the new partition UUIDs for ROOT-A and ROOT-B in the root=
kernel parameters provided by the legacy (non-kexec) bootloaders. This
makes all of our images bootable as-is without having to pass them
through image_to_vm.sh. :-D
As outlined here we need a new partition layout, this patch makes the
necessary changes:
https://groups.google.com/forum/#!topic/coreos-dev/bA7gwGGoTng
The first big change is making all of the scripts obey partition numbers
based on labels in the disk_layout.json. This makes it much easier to
change later on.
The second big change is in the layout itself. The json file was updated
to reflect the document above.
And finally the grub boot configuration needed for pv-grub and pygrub
were added to the create_legacy_bootloader_templates.sh library utlity.
Everything seems to work and boot now.
on Fedora 18 on Gnome 3.0 something is making the first attempt at
unmounting return busy. Unfortunatly, the return code is 32 everytime
so we have to parse the output of umount :( :( :(

When changing the size of the stateful partition, we must be able to
operate on any image, with any arrangement of partitions. The static
templates cannot be used because we don't know what we're starting with.
As such, this change makes the update function walk the list of
partitions, duplicating all their details, and moves any located after
stateful by the change in size, and copies in the new stateful contents.

The "update_partition_table" routine is used by mod_image_for_recovery.sh
and ~/trunk/src/platform/dev/host/tests/mod_recovery_for_decryption.sh.
This moves the routine into a common location so future changes will not
break things. Additional removes the duplicate okboat/failboat
definitions from mod_image_for_recovery.sh since those are in a common
place already.
This change does not fix the stateful resize logic part of the bug, but
does move the code into a single place so mod_recovery_for_decryption.sh
can use it once it has been fixed.

This change adds support for building the disk layout from a
configuration file. It also cleans up much of the image creation
code.
install_gpt no longer exists, and has been replaced by cgpt.py's
write action. This spits out a file that has two functions that can
be called to write a partition layout to a disk/file. This gets rid
of the gigantic nest of calculations that built the layout previously.
All instances of partition/filesystem sizes in build scripts should now
be gone in favour of calls to the cgpt.py tool.
create_boot_desc has moved inside the base image creation, in an effort
to simplify build_image.
load_kernel_test is gone since it's apparently not supposed to be called
here anyway (asked wfrichar/rspangler about this one).
Base image creation now uses files rather than loop devices when
building an image. This means we can simply umount them once we're
done and not worry about cleaning up the loop device, since it's
been done for us.
Hash pad calculation has been removed. This is now set manually inside
the partition config file.
Hybrid MBR creation is gone, since it's now possible to do that in a board
specific hook (see overlay-beaglebone/scripts/board_specific_setup.sh).
OEM partition now has a filesystem, which is mounted at /usr/share/oem
during emerge so that packages can stash files here.
root_fs_dir and friends are still globals, but the long-term idea
is to make this not the case.
