Linux: Partition Options

Description

The Linux: Partition Options test is used to check the information associated with partitions on the local system.

The partition_object is used by a partition_test to define which partitions on the local system should be collected.

The partition_state element defines the different information associated with a partition. This includes the name, filesystem type, mount options, total space, space used, and space left.
