X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=999eeed90f8e614cad8f52657d5fc4b3a611213e;p=thirdparty%2Fcoreutils.git

chmod, install, and mkdir now leave setgid and setuid bits
of directories alone unless you specify them explicitly.
install and mkdir now implement X correctly.
install now creates parent directories with mode 755, without
changing their owner or group.

+  chmod, install, and mkdir now leave a directory's set-user-ID and
+  set-group-ID bits alone unless you explicitly request otherwise.
+  This is for compatibility with BSD and other systems.  For example,
+  `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.  If
+  you want to clear the bits you can mention them explicitly, e.g.,
+  `chmod 0755 DIR' and `chmod a-s,u=rwx,go=rx DIR'.

   `cp --link --no-dereference' now works also on systems where the
   link system call cannot create a hard link to a symbolic link.
   This change has no effect on systems with a Linux-based kernel.

   used only for internal errors (such as integer overflow, which expr
   now checks for).
 
+  install and mkdir now implement the X permission symbol correctly,
+  e.g., `mkdir -m a+X dir'; previously the X was ignored.
+
+  install now creates parent directories with mode u=rwx,go=rx (755)
+  instead of using the mode specified by the -m option; and it does
+  not change the owner or group of parent directories.  This is for
+  compatibility with BSD and closes some race conditions.

   ln now uses different (and we hope clearer) diagnostics when it fails.
   ln -v now acts more like FreeBSD, so it generates output only when
   successful and the output is easier to parse.
