Comment 6 Adam Williamson 2012-11-01 20:41:56 UTC
Nominating as NTH for F18 Beta; it's a security bug in kernel, that's on the path that can't be fixed entirely by an update (vuln will still be in installer and live images).

Comment 7 Jaroslav Reznik 2012-11-01 20:48:26 UTC
+1 to NTH as it's security issue and can't be fixed by update.

Comment 8 Jóhann B. Guðmundsson 2012-11-01 21:23:58 UTC
+1 to NTH as it's security issue and can't be fixed in the installer without updating the kernel there.

Comment 9 Tim Flink 2012-11-01 21:29:58 UTC
+1 F18 beta NTH as it's a security issue that can't be fixed in the installer or livecds with an update

That makes +4 (assuming +1 from Adam), moving to AcceptedNTH

Comment 10 Adam Williamson 2012-11-08 09:43:23 UTC
We have a much newer kernel stable now, for 17 and 18 at least. Closing. (Bodhi closing of bugs when updates go stable is currently broken).
