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.
The linux-info eclass may trigger a fatal error if it is unable to check
a package's required kernel options. Even when the error isn't fatal the
warnings add a lot of clutter to our build output.
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.
