Check Text ( C-42343r1_chk )
Check the root account's home directory has no extended ACL.

# grep "^root" /etc/passwd | awk -F":" ‘{print $6}’

# ls -ld

If the permissions include a '+' the directory has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.
Fix Text (F-38335r1_fix)
Remove the extended ACL from the root account's home directory.
# setfacl --remove-all
