I don't see this behavior with my Dec 22nd kernel, so it must have come in after that. I did notice that the sticky bit had interesting behavior, however, when I first tried this as an average user: jkh@whisker-> cp /bin/sh /tmp jkh@whisker-> echo echo hello there | /tmp/sh hello there jkh@whisker-> cp /bin/sh /tmp cp: /tmp/sh: Permission denied Hmmm. I thought it was only supposed to refuse this request if somebody *else* tried to replace my file in /tmp! :-) Jordan
