RHEL 10 must use a separate file system for "/var/tmp".

The "/var/tmp" partition is used as temporary storage by many programs. Placing "/var/tmp" in its own partition enables the setting of more restrictive mount options, which can help protect programs that use it.

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

$ mount | grep /var/tmp /dev/mapper/luks-c98555c8-0462-4b97-9afa-6db8c4bfee3b on /var/tmp type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2) Note: Options displayed for mount may differ.

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

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