Systemd has the ability to manage mounts and ensure functionality
/ resource management. Using a systemd mount has the benifit of not
requiring writes to the legacy fstab file which can impact OS
functionality especially when deploying on baremetal. This change
moves the glance NFS mount to a systemd unit file allowing systemd
to manage it independently with no potentially breaking impact to
the underlying operating system.
Changes:
- This PR corrects a long standing issue when using Glance+NFS where
initial deployment would work but if the playbooks were run again
it would fail due to the glance images location being an NFS mount
point with a potentially different UID/GID. To correct this we stat
the directory and if it does NOT exist it is created.
- Following the nova pattern options have been provided to set the UID
and GID of the glance user.
- To ensure out NFS backend solution works with the installation of
glance a test has been added to deploy glance using an NFS backend.
- An upgrade task has been added to this commit to clean up legacy
mounts, This task should be removed in R.
