--oLBj+sq0vYjzfsbl Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Prompted by some discussion elsewhere, I've been trying to send SIGKILL to init. If I ktrace kill(1), I can see "kill(1,9)" which returns 0 but the signal is never delivered. If I sent (eg) SIGXCPU then init dies and the kernel panics (as expected). I've looked through sys/kern/kern_* and can't see anywhere that special cases the delivery of SIGKILL to init. Can anyone please explain why SIGKILL doesn't kill init (at least on -stable). --=20 Peter Jeremy --oLBj+sq0vYjzfsbl Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFFD6KG/opHv/APuIcRAvBCAJ40ObuxklNZn5sFdzfxnjY3SkUmjgCeNZiJ szexJpQszDVVHhtCQ+TC2jg= =37qi -----END PGP SIGNATURE----- --oLBj+sq0vYjzfsbl--
