The machinectl cache is currently set image to 16G by default. If multiple container images are imported into the cache this may be too small by default. This change sets the cache to "64G" by default allowing the cache more room to grow by. This change also disables the quota system once the limit has been set The option `lxc_host_machine_quota_disabled` has been added to disable or enable the quota system as needed. This is done after the default limit has been set so an adequately sized sparce file can be created should it not already exist. > More documentation can be seen here [0] with regard to the set-limit option. Because we support both modern and older systemd, the cache prep tasks for old systemd have been updated so that deployers using earlier versions of systemd can benefit from the ability to grow an existing cache via playbook run.
