From 0ab4e02509f91581a4ade9eee78f4279adc8232f Mon Sep 17 00:00:00 2001 From: Alexandru Avadanii Date: Thu, 9 Jun 2016 20:36:38 +0200 Subject: post-scripts: Enable systemd-binfmt for first boot. 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: . 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.
