- "./build_image prod" already has the ability to specify which package will specify all the packages that should be pulled in and built into an image by specifying a package name using the --base_pkg command line flag. This creates an equivalent option for "./build_image dev" creating a --base_dev_pkg flag that passes a package name into the create_dev_img() function in dev_image_util.sh the same way that --base_pkg is passed into create_prod_image() inside prod_image_util.sh.
This change changes the default 'bytes-per-inode' ration from 16K to 4K,
the block size. To prevent this from wasting too much space change the
inode size from the default 256 to the minimum size, 128. Larger inodes
are used to store extended attributes more efficiently but since we do
not use SELinux the majority of files do not have security attributes.
These defaults may be modified via the new `bytes_per_inode` and
`inode_size` options.
Fix parsing the following output:
[ebuild N ] dev-libs/gmp-5.1.3-r1 to /usr/x86_64-cros-linux-gnu/
[ebuild UD] sys-libs/timezone-data-2013d [2014i-r1] to /usr/x86_64-cros-linux-gnu/
The previous regex did not account for upgrades and got confused by the
`[2014i-r1]` listing and goobbled up too much of the string. I am not
sure *why* portage is reporting an upgrade when --emptytree is also used
but there it is. Match all not-] characters instead.
Disable ccache as it is causing issues in other builds so disable it
everywhere to be safe. Disable the autoresume feature because our build
process doesn't actually make use of it.
Adding the update step appears to break permissions on the distfiles
directory. Ensure the portage user is correct and set the permissions on
directories it needs to write to in advance.
When bootstrapping a SDK we need to update GCC dependencies to ensure
the GCC built for stage1 is linked against the same library versions as
those that are included in the stage1. Without this updating the mpc
library just results in a broken stage1.
Probing all filesystem types on all block devices appears to hang
booting Amazon EC2 HVM instances. The console output is unreliably
buffered so there is no information on what the failure actually is. On
the up side we can work around it easily by only searching the GPT which
appears to be safe.
To aid testing things under Xen it helps to have a machine locally that
actually runs Xen! This isn't a particularly great setup but it works
well enough to simplify my own testing. Must be used with a developer
image and packages built with `USE=vm-testing` set to include the Xen
userspace tools.
This uses our new GRUB2 features to handle GPT priority partition
selection, terminal selection, OEM tweaks, etc. The old SYSLINUX and
PV-GRUB configs are now unused except for maintaining compatibility
with older installs. Of the old configs only the ones that
coreos-postinst copies are needed. The new setup supports using GRUB2
under Xen, giving us automatic fallback support on all of our platforms
for the very first time!
Since grub.cfg is copied into place instead of generated, build_image's
--boot_args option is no longer supported. It could be re-added later
with some sed goo but for now it is easy enough to just edit grub.cfg.
Mark the initial copy of CoreOS as 'successful' and with a non-zero
priority. Required to boot with a stricter interpretation of the
partition selection scheme which ignores partitions that have a priority
of zero. The new grub implementation follows this rule and is what the
original ChromeOS spec used too.
For the sake of completeness if multiple partitions are configured in
the json file with this feature they will be prioritized in disk-order.
The VHD format actually uses 2MB blocks internally so the 1MB alignment
used in e77e4e54 wasn't sufficent to prevent other tools from further
adjusting the image size to align it. Additionally a 1MB alignment may
be triggering a bug in OpenStack or XenServer disk resizing that renders
that partial block at the end of the old image size unmapped/unavailabe.
So far the default iteration order of python dicts has mostly matched
the order that we want the partitions on disk but this is not always the
case. I caught the BIOS-BOOT partition being ordered on disk after the
USR-A partition. Nothing bad came of this but consistancy is good.
The new disk size alignment left too much extra space at the end of the
disk which would lead to pointless resizing on first boot. Fill in the
extra space so that no more than 1MB is left unused.
The VHD disk format internally includes CHS addressing and qemu-img
respectfully aligns disk images to the common 16 heads 63 sectors
geometry when possible. This is unfortunate since images uploaded to
Azure must also be aligned to 1MB we normally do.
Since qemu-img doesn't have a way to handle this well right now adjust
our existing alignment logic to create disk images aligned to both.
I am unsure exactly what situation is causing the loopback partition
device node to not exist when it is being mounted but this should help
work around the situation and log loudly about it so we can hopefully
figure out where to dig further.
Version 4 is too low. Some VMware products even crash trying to
upgrade it to a greater version (VMware Fusion 6 Pro). Having at
least 7 will allow us to use some modern features in most VMware
products, such as enabling vmxnet3 virtual network adapters or adding
much more memory and cpu cores to virtual machines.
Pruning files via INSTALL_MASK in the profile is a bit more apropriate
since it allows us to keep most of that info in one place. The only
parts that need to be deleted or adjusted here are inputs and outputs of
`env-update` which has to be run after everything is installed.
Previously we didn't actually clean up `env.d` at all which lead at
least one user to think they should edit those files and run
`env-update` themselves but we don't ship that tool on prod images.
This sets the IMG_FORCE_OEM_PACKAGE variable to the supplied string. If a
':' is present, what follows it gets put in the IMG_FORCE_OEM_USE variable
and what precedes in the former.
_get_vm_opt() has been modified to generally support forced overrides such
as this one, simply set variables named IMG_FORCE_$opt.
Now you can do things like:
for fmt in cloudstack \
digitalocean \
ec2-compat:ec2 \
ec2-compat:openstack \
ec2-compat:brightbox \
exoscale \
gce \
hyperv \
rackspace \
rackspace-onmetal; do
./image_to_vm.sh --format=qemu --oem_pkg=$fmt
../build/images/amd64-usr/latest/coreos_developer_qemu.sh -curses
done
rather than having to modify build_library/vm_image_util.sh to test oem
builds in qemu.
