Feature changed by: Luis Freitas (jazzmelody) Feature #309205, revision 7 Title: Remove old kernel package only after the new one successfully booted openSUSE-11.2: Rejected by Andreas Jaeger (a_jaeger) reject date: 2010-03-24 09:37:10 reject reason: 11.2 is long out, let's file for 11.3. Priority Requester: Important openSUSE-11.3: Rejected by Federico Lucifredi (flucifredi) reject date: 2010-05-28 17:33:45 reject reason: Too late. Priority Requester: Important openSUSE-11.4: Evaluation by project manager Priority Requester: Important + Requested by: Luis Freitas (jazzmelody) Requested by: Martin Barry (supine) Product Manager: (Novell) Product Manager: (Novell) Project Manager: (Novell) Partner organization: openSUSE.org Description: When the kernel package is upgraded the old one is immediately removed leaving the currently running kernel with no modules. This breaks anything that requires modules until the user has an opportunity to reboot. The removal of the old package should be delayed till the system is rebooted into the new kernel. Reproducible: Always Steps to Reproduce: 1. Kernel package is upgraded 2. Try to run tcpdump Actual Results: 3. Get error about "interface not supported" and "unknown address family" 4. Reboot into new kernel 5. Try again to run tcpdump with identical arguements 6. tcpdump works as expected Expected Results: 3. tcpdump works as expected even before system is booted into new kernel Relations: - Kernel upgrade removes modules of running kernel subtly breaking the system until rebooted into new kernel (novell/bugzilla/id: 590496) https://bugzilla.novell.com/show_bug.cgi?id=590496 Discussion: #1: unknown user (2010-03-23 14:38:59) This is another symptom of needing the ability to clean up an old kernel after a successful boot. #2: (michal-m) (2010-03-23 16:02:38) (reply to #1) Let alone defining "successful boot" would be tough, but let's say if the user has logged in, there is at least some success (but e.g. the network might still not be working though). This would be the kernel packaging part. Then there would need to be some way to tell the package manager "now it's time to remove packages x,y and z, ask the user for confirmation either via the update applet, or as soon as the package manager is started". IMO it would be a nice feature, but I have no idea how difficult the zypp/yast/updater applet part would be. + #6: Luis Freitas (jazzmelody) (2011-04-16 02:36:19) (reply to #1) + I use OpenSUSE in a production environment for server purposes and this + is a very important (and secure) feature that is needed + professionally. #5: Martin Seidler (pistazienfresser) (2010-11-01 10:34:11) See also: # for Ubuntu: last-good-boot https://wiki.ubuntu.com/KernelTeam/removing-old-kernels (https://wiki.ubuntu.com/KernelTeam/removing-old-kernels) # other openFATE Treads: ## #310665: Keep the current kernel when doing a kernel update through yast https://features.opensuse.org/310665 ## #306971: keep the previous kernel after update process https://features.opensuse.org/306971 (306971) -- openSUSE Feature: https://features.opensuse.org/309205
