Check Text (C-269301r1050183_chk)
Verify that a separate file system/partition has been created for "/tmp" with the following command:
$ mount | grep ' /tmp '
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noexec,relatime,seclabel,size=2097152k,inode64)
If a separate entry for "/tmp" is not in use, this is a finding.
