The PodmanOptionsKey is never used anywhere so it is pointless to add this. Second having several functions to return the same context makes no sense so fold them all into one. Lastly create the context once and always return the same one instead of having to nil check each time. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

When a container is unmounted, the mount counter is decremented. The container's root filesystem is physically unmounted only when the mount counter reaches zero indicating no other processes are using the mount.

An unmount can be forced with the --force flag.
