Fix Recommendation

Configure RHEL 10 to use a separate file system for the "/var" directory by migrating the "/var" path onto a separate file system.

Check Contents

Verify RHEL 10 uses a separate file system/partition for "/var" with the following command:

$ mount | grep /var
/dev/mapper/luks-51150299-f295-4145-b8f0-ebe9c6dfd5a0 on /var type xfs (rw,nodev,relatime,seclabel,attr2)
Note: Options displayed for mount may differ.

If a separate entry for "/var" is not in use, this is a finding.
