Check Text (C-257846r1044922_chk)
Verify that a separate file system/partition has been created for "/var/log" with the following command:
$ mount | grep /var/log
/dev/mapper/rhel-var_log on /var/log type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k)
Note: Options displayed for mount may differ.
If a separate entry for "/var/log" is not in use, this is a finding.
