Arches please mark 4.12 stable.

Target KEYWORDS="alpha amd64 arm hppa ia64 mips ppc ppc64 s390 sh sparc x86"

Note to sh: no arch alias exists so someone (vapier?) please mark it sh.

------- Comment #6 From Gustavo Zacarias (RETIRED) 2004-12-07 06:16:34 0000 -------
sparc stable.

------- Comment #7 From Mike Doty 2004-12-07 06:33:58 0000 -------
stable on amd64

------- Comment #8 From solar 2004-12-07 08:32:27 0000 -------
stable on x86

------- Comment #9 From Daniel Black 2004-12-07 13:13:48 0000 -------
ppc stable.

------- Comment #10 From Joshua Kinard 2004-12-08 01:36:56 0000 -------
mips can't stable this revision unless we can get the
file-4.xx-mips-gentoo.diff patch to apply, otherwise, file gives bad output on
mips systems that mess up configure scripts.

The interesting thing is, the patch applies fine outside of portage, but
applying within the ebuild, the dry-run sweep creates .orig files that cause
epatch to fail on the second pass.  We got a workaround for this?

------- Comment #11 From Bryan Østergaard (RETIRED) 2004-12-08 02:29:13 0000 -------
Alpha stable.

------- Comment #12 From Joshua Kinard 2004-12-08 03:01:28 0000 -------
Okay, disregard Comment #9; seems the patch we use it responsible for the .orig
file breaking things.  Will fix && stabilize in the morning.

------- Comment #13 From Hardave Riar (RETIRED) 2004-12-08 13:14:03 0000 -------
Stable on mips.

------- Comment #14 From Guy Martin 2004-12-10 04:50:11 0000 -------
Stable on hppa.

------- Comment #15 From Thierry Carrez (RETIRED) 2004-12-10 08:31:51 0000 -------
ppc64 please mark stable so that the GLSA can go out.

------- Comment #16 From Markus Rothe 2004-12-10 23:35:29 0000 -------

learn to use bugzilla :P (error filed as Bug 73786)

------- Comment #21 From Jeremy Huddleston (RETIRED) 2004-12-13 22:35:42 0000 -------
vapier: That bug is preventing this security bug from being resolved
(regardless of whether or not you mark it 'RESOLVED' because a secure package
is not available to our users who can't emerge it.

That bug should have been resolved before this was marked stable.

------- Comment #22 From Sune Kloppenborg Jeppesen 2004-12-13 23:44:30 0000 -------
eradicator: I agree this should have been fixed before if we were alerted to
the fact that there was a bug.

------- Comment #23 From Jeremy Huddleston (RETIRED) 2004-12-14 00:20:58 0000 -------
bug #73786: 2004-12-08 04:17 PST
GLSA:       2004-12-13 14:47 PST

The bug was filed 5 days before the GLSA was announced.  base-system should have mentioned this problem here and dealt with it so the GLSA could be released...

eradicator: you're right however base-system is not on this bug and security
were only just alerted:
