Comment 7 Adam Williamson 2012-11-01 16:42:37 EDT
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 8 Jaroslav Reznik 2012-11-01 16:48:58 EDT
+1 to NTH as it's security issue and can't be fixed by update.
Comment 9 Jóhann B. Guðmundsson 2012-11-01 17:24:07 EDT
+1 to NTH as it's security issue and can't be fixed in the installer without updating the kernel there.
Comment 10 Tim Flink 2012-11-01 17:29:04 EDT
+1 NTH as it's a security issue that can't be fixed by an update

THat makes +4 (assuming +1 from Adam), moving to AcceptedNTH
Comment 11 Adam Williamson 2012-11-08 04:43:32 EST
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).
