Emilien Macchi fb0ec2ffd0 (backward compatibility) create kolla UIDs/GIDs for TCIB ... When upgrading container images from Kolla-based to TCIB-based, the config files can't be read if we don't apply the new chown values unless we re-use the same UIDs/GIDs as we had with Kolla; which is what we'll do for now until we figure out an easy way to update config permissions during the upgrade/update stage. This introduces a new script, that will be injected in the base layer: uid_gid_manage.sh Usage: ./uid_gid_manage.sh qemu nova It'll first create the qemu user/group, then nova user/group. The format aims to be simple: <username> <uid> <gid> <optional homedir> <optional list of extra groups> It's also removing instances of usermod which aren't needed anymore; since we create the user / groups only in the images where they are needed; which wasn't the case for Kolla where all users/groups were created in the base image. Note: we create the user/group before installing packaging so if packaging creates directories and sets permissions, it'll be with the right UID/GID (unless packaging overrides UID/GID but rarely do it).
