Only the key is needed, and currently the vagrant OEM is completely
broken outside of vagrant. This gets vmware_insecure images back into
the state that they were before cloud config came along. :)
The existing version.txt is kinda annoying. The common case of referring
to the current version requires joining three values and the names of
those values only make sense in ChromeOS. Instead just use version as a
string, using VERSION, VERSION_ID, and BUILD_ID just as they appear in
os-release. It is up to the few scripts that need the individual parts
to break the version apart.
The old values remain for the sake of compatibility.
This adds two new optional build steps. The first user of these is the
vagrant images but many of the targets can be simplified now.
- fs_hook: Anything that needs to happen before unmounting the image.
This happens after the OEM is installed but before disk images are
made. It can be used to copy any data out of the image.
- bundle_format: Many VM types ship as some sort of archive format
rather than plain disk images as this script originally assumed.
Adding this final step lets us stop using the conf step awkwardly.
Vagrant now ships with a Vagrantfile and related code included in the
OEM package. This lets us version our vagrant-side code along with the
images themselves as well making the coreos-vagrant repo optional again.
The coreos-vagrant code will still be useful for handling the fancier
cluster configuration stuff but no longer has to carry the plugin code.
This should make it less difficult for people to add kernel options for
debugging. Without a prompt/timeout the user must be holding down space
or some other key while syslinux loads but it may not be possible for
the user to do so provide input quite that fast. Only a half second to
avoid needlessly increasing boot times in the common case.
Using the classic mbr.bin was only needed during the transition from
syslinux 3 to 6 because the behavior of gptmbr.bin changed after 3.
Now that the transition is done and cgpt supports the new scheme now it
is time we switched back. This avoids depending on using a hybrid MBR.
The .DIGESTS format is clunky and annoying. It also requires uses to
perform two steps to verify images using GPG. Instead support signing
all files directly so there is no need for .DIGESTS.
The old DIGESTS code will remain in place for now but after a few
releases I plan on deleting it.
The latest release of portage uses repos.conf, so generate that
file when making the chroot. The crossdev overlay also needed
repo_name and layout.conf files.
The use of getopts was leading to conflicts between this script's short
options and qemu's long options. For example -serial was getting
interpreted as -s -- erial which is not very helpful.
