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
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

- Kernel upgrade removes modules of running kernel subtly breaking the
system until rebooted into new kernel (novell/bugzilla/id: 590496)

This is another symptom of needing the ability to clean up an old
kernel after a successful boot.

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.
