ARMBAND NOTE(S):
- This is a bug fix + a new feature (arch list in a file on FM)
- This is overengineered because:
* we want to move patching to post-ISO creation, OPNFV style;
* easier integration with Fuel@OPNFV, using post-install scripts;
* prepare for true multiarch support on Fuel Master;
IMPORTANT:
This commit introduces the following file on Fuel Master,
containing the list of arch supported for target nodes:
</etc/fuel_openstack_arch>.
This file is created AFTER pre.d OPNFV scripts are ran, also by
bootstrap_admin_node.sh, BEFORE the post.d scripts are executed.
NOTE: Arch format is the same used by dpkg (e.g.: "amd64 arm64")
Based on the number of foreign architectures we should support
(the list of archs in /etc/fuel_openstack_arch minus native arch),
we determine whether cross-builds are expected, in which case
binfmt support should be functional during first Fuel Master boot.
Since systemd-binfmt service has a series of preconditions for
starting, which are tested early during first boot, some of them
are NOT YET true (e.g. no binfmt handlers are present before
qemu-user-static package is installed), so the service is not
automatically started. Of course, this only affects the first boot.
Finally, this commit adds an OPNFV post-install script in
/opt/opnfv/bootstrap/post.d, which starts systemd-binfmt service.
