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

Verify that a separate file system/partition has been created for SLEM 5 nonprivileged local interactive users (those with a UID greater than 1000) home directories with the following command:

     > awk -F: '($3>=1000)&&($7 !~ /nologin/){print $1, $3, $6, $7}' /etc/passwd
     disauser 1002 /home/disauser /bin/bash
     dosuser 1003 /home/dosuser /bin/bash
     dosuser 1001 /home/dosuser /bin/bash

The output of the command will give the directory/partition that contains the home directories for the nonprivileged users on the system (in this example, /home) and user's shell. All accounts with a valid shell (such as /bin/bash) are considered interactive users.

Check that a file system/partition has been created for the nonprivileged interactive users with the following command:

Note: The partition of /home is used in the example.

     > grep /home /etc/fstab
     UUID=c4e898dd-6cd9-4091-a733-9435e505957a /home btrfs defaults,subvol=@/home 0 0

If a separate entry for the file system/partition that contains the nonprivileged interactive users' home directories does not exist, this is a finding.

Fix

Create a separate file system/partition for SLEM 5 nonprivileged local interactive user home directories.

Migrate the nonprivileged local interactive user home directories onto the separate file system/partition.
