setfacl(1) manual does not specify what happens when a user uses chmod(1) command over a file with ACL entries set. Fix: The manual should describe a situation when a file is manipulated with chmod(1). That would be appropriate: If you use the chmod(1) command to change the file group owner permissions on a file with ACL entries, both the file group owner permissions and the ACL mask are changed to the new permissions. Be aware that the new ACL mask permissions may change the effective permissions for additional users and groups who have ACL entries on the file.
