cgpt now supports generating hybrid MBRs and the classic style mbr.bin
from any version of SYSLINUX should work the same with the hybrid MBR.
The other code, gptmbr.bin, changes after SYSLINUX 3. Switching lets me
play with different versions of SYSLINUX without breaking everything.
With this change all images feature a hybrid MBR so the special case for
some VM platforms has been removed.
To avoid having to sync directory creation and tmpfiles installed by
ebuilds just require ebuilds to do `keepdir /etc/path` and this script
will handle the rest. A possible extension would be to update to handle
symlinks in addition to directories in gen_tmpfiles.py
The boot kernel parameters change depending on whether the new /usr
scheme is in use. Pass the disk layout to the bootloader config script
and adjust generated configs accordingly.
cros_make_image_bootable now only is relevant for prod images, so move
the remaining code to prod_image_util in a similar scheme that base and
dev images use.
The verification flag was being passed through to the bootloader
template script but no longer had any effect.
Force the base image to always remain writable, its only purpose is to
be modified in a later build step anyway.
This isn't a feature we've been using as far as I know and if someone
needs a custom partition layout it's probably better to just add it to
the json file. Removing this avoids some complexity.
Move from optparse to argparse. Move layout file and layout type to
global options with reasonable default values so every command doesn't
need to them. Adjust calling scripts to match.
For now layout type is being passed via an environment variable
DISK_LAYOUT_TYPE but this is a temporary situation.
Previously the code in base_image_util.sh properly handled the disk
layout command line flag but the spaghetti code later on calls a
function from disk_layout_util.sh which only returned 'base' resulting
in a bit of a mess if something other than 'base' is used. Sync up the
two code paths to avoid that...
We don't have any particular reason for the weird hackery required to
install packages into /usr/local instead of root. The rootfs image is
already being modified a little might as well modify it a lot. :)
This reverts commit b97cfe126f.
The minor device numbers of loop partitions are allocated dynamically
which significantly complicates dunning under Docker which uses a static
/dev. Rolling this back until we can rely on /dev being dynamic.
This avoids the need to dd individual filesystem images into a complete
disk image, just mount the partitions directly from a loop device
covering the whole image. This does add the requirement that mkfs run as
root but that isn't a problem.
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.
As of Linux 3.2 loopback supports discard by punching holes in the
underlying file. This doesn't actually seem to impact things right now
since we are writing to fresh filesystems but might as well do this to
prevent wasted space from sneaking in later on.
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.
/mnt/stateful_partition was already a little unruly with
/mnt/stateful_partition/home and /mnt/stateful_partition/var_overlay
serving similar functional purposes.
Then we needed to also add /opt and /srv overlays.
I also have wanted to get rid of the ugly and weird
/mnt/stateful_partition name so lets just have one big move.
/mnt/stateful_partition -> /media/state
/mnt/stateful_partition/var_overlay -> /media/overlays/var
/mnt/stateful_partition/home -> /media/overlays/home
From there we add /media/overlays/srv and /media/overlays/opt
The basic system directory structure including the lib symlinks were
fixed for sysroot in the following commits but the image build uses an
entirely different bit of code to do the exact same set of hacks. Port
those changes to the image building code to hopefully make all happy.

A few things here:
- Source manifests/version.txt directly instead of coreos-version.sh
- Remove Chrome branch from target image directory names.
- Use proper version instead of timestap for catalyst builds.
- Move lsb_release script from coreos-overlay to build_library.
During builds var_overlay is always mounted over /var. We want to do the
same at run time but we also want to ensure everything expected to be
there always does. After emerge completes gen_tmpfiles.py will scan /var
for any .keep files that were installed and records their parent
directories' permissions and ownership to /usr/lib/tmpfiles.d. On each
boot systemd will automatically recreate anything that goes missing.
This also means that going forward any ebuild that needs a directory in
/var (or anywhere else the stateful partition is bound) can simply rely
on the 'keepdir' ebuild function instead of adding things to
coreos_startup.
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.
The latest coreutils introduces a status=none option which suppresses
all information which is more than the current status=noxfer.
