Oops, you're right---I meant swapping of struct user. Presumably there's nothing magic about init's pcb and kstack, though. > P.S. Your Mail-Followup-To: header may be considered offensive. In the absence of a Mail-Followup-To or Reply-To header in the message I'm replying to, mutt seems to generate a Mail-Followup-To for everyone but me (since it knows I'm subscribed and wants to direct others not to CC me.) It doesn't know if anyone else wants a CC or not because they didn't use Mail-Followup-To, so it includes them by default. I think this is what it's supposed to do, but if you know of a knob that I ought to turn, let me know. _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
