TASK [command mount-a] *********************************************************
[WARNING]: Consider using the mount module rather than running 'mount'. If
you need to use command because mount is insufficient you can add 'warn: false'
to this command task or set 'command_warnings=False' in ansible.cfg to get rid
of this message.
