Thanks for the report. This is fixed upstream, in coreutils-5.3.0. For reference, here's what I did to show that: # touch f # chown 1:2 f # ln -s f slink # ./chown --deref 4 slink # stat -c '%g' f; echo 2 # /bin/chown --deref 4 slink # stat -c '%g' f; echo 0 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
