This can be used by update_engine as a quick test to determine if it is
running on a system that it can handle. This avoids needing something
like the 'coreos.diskless' kernel command line flag.
If QEMU is given a uuid systemd will detect that and in turn use it for
the machine-id. This made the bug causing the machine-id to be always
re-generated on boot harder to notice since it didn't happen on QEMU.
Taking a bit of a new approach to booting PXE images here for both
amd64-generic and amd64-usr. Instead of requiring the user to specify
squashfs and tmpfs on the kernel command line we can simply provide
defaults in the initrd's fstab.
Now with SYSLINUX 6 we can use the same bootloader on EFI and BIOS
systems. This replaces our previous reliance on building default kernel
options into the kernel image itself.
- Remove custom COREOS_* attributes from /etc/lsb-release
- Move dev image logic to dev_image_util
For extra fun fix detection of local host URL for devserver.
- Remove weirdly verbose "DESCRIPTION" format.
- Add COREOS_RELEASE_BOARD back to /usr/share/coreos/release
This is mostly just so update_engine and gmerge report the correct
board name to devserver, informative-only on prod images.
- Remove version info from /etc/gentoo-release
- Switch from 'track' to 'group' terminology.
Fix the problem of: "pecified switch root path %s does not seem to be an
OS tree. /etc/os-release is missing" because dracut doesn't have an
/usr/share/coreos/os-release file.
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.
This doesn't make things go faster and I am suspicious that it makes
things worse. For example /etc/xml/catalog winds up empty from time to
time and I wonder if this locking is related to that.
While attempting to fix the easy to mix up DIGESTS names in feb59db9f I
stumbled across yet another way that the DIGESTS names were a bit
unpredictable: previously a .bz2 got stuck into the file name when
upload_images automatically compressed some file types. The new code
missed this and never added the .bz2. Correct this now, both for
image_to_vm which has a pile of glue to keep the legacy names in place
for now and build_image which I never intended to change.
Vagrant reads this file to determine that we are CoreOS... so lets not
break that just yet. A PR to switch to os-release has been posted:
https://github.com/mitchellh/vagrant/pull/2985
Some day gentoo-release will be dropped but that day is not today.
