Ah, oh. I didn't know this. This actually violates the principle of least surprise in my eyes, but hey, if it is documented, I am ok with it. Thinking some more about it, isn't the behaviour then wrong by clearing the set-uid bit? The doc says: If you want to try to clear these bits, you must mention them explicitly in a symbolic mode, e.g.: But if I review my example, then I first set suid+sgid, then do a chmod 0 and suid is still set, but not suid: d...@ohwell:tmp[0]$ mkdir foo ; $p/chmod 3777 foo ; ls -ld foo ; $p/chmod 0 foo ; ls -ld foo drwxrwsrwt 2 dzu dzu 4096 2009-03-13 15:28 foo d-----S--- 2 dzu dzu 4096 2009-03-13 15:28 foo Isn't this still a bug alas the other way round then I originally thought?
