Hi, The (RHEL 7) man page for GNU 'chown' has (only) this for the '--reference' flag: use RFILE's owner and group rather than specifying OWNER:GROUP values which omits the crucial second sentence, included in the info tree: Change the user and group of each FILE to be the same as those of REF_FILE. If REF_FILE is a symbolic link, do not use the user and group of the symbolic link, but rather those of the file it refers to. (Note that '--no-deference' doesn't affect this behavior.) I can't be sure, but I think the GNU build itself is generating this man page, as opposed to it having been created by RHEL. I understand that the man pages are secondary and brief, but they shouldn't be actively misleading, IMO.
