Title

SLEM 5 must use a separate file system for /var. (Cat II impact)

Discussion

The use of separate file systems for different paths can protect the system from failures resulting from a file system becoming full or failing.

Check Content

Verify that SLEM 5 has a separate file system/partition for "/var" with the following command: > grep /var /etc/fstab UUID=c4e898dd-6cd9-4091-a733-9435e505957a /var btrfs defaults,subvol=@/var,x-initrd.mount 0 0 If a separate entry for "/var" does not exist, this is a finding.

Fix Text

Create a separate file system/partition on SLEM 5 for "/var". Migrate "/var" onto the separate file system/partition.
