Yes, that's mentioned in the NEWS file. It says: chmod, install, and mkdir now preserve a directory's set-user-ID and set-group-ID bits unless you explicitly request otherwise. E.g., `chmod 755 DIR' and `chmod u=rwx,go=rx DIR' now preserve DIR's set-user-ID and set-group-ID bits instead of clearing them, and similarly for `mkdir -m 755 DIR' and `mkdir -m u=rwx,go=rx DIR'. To clear the bits, mention them explicitly in a symbolic mode, e.g., `mkdir -m u=rwx,go=rx,-s DIR'. To set them, mention them explicitly in either a symbolic or a numeric mode, e.g., `mkdir -m 2755 DIR', `mkdir -m u=rwx,go=rx,g+s' DIR. This change is for convenience on systems where these bits inherit from parents. Unfortunately other operating systems are not consistent here, and portable scripts cannot assume the bits are set, cleared, or preserved, even when the bits are explicitly mentioned. For example, OpenBSD 3.9 `mkdir -m 777 D' preserves D's setgid bit but `chmod 777 D' clears it. Conversely, Solaris 10 `mkdir -m 777 D', `mkdir -m g-s D', and `chmod 0777 D' all preserve D's setgid bit, and you must use something like `chmod g-s D' to clear it. _______________________________________________ Bug-coreutils mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-coreutils
