Constructor Details

This class inherits a constructor from Chef::Provider::Mount::Mount

Instance Method Details

#loop_mount_points ⇒ Object

Check to see if the volume is mounted. “findmnt” outputs the mount points with volume. Convert the mount_point of the resource to a real path in case it contains symlinks in its parents dirs.
