The installonlyn plugin is a bit too naive when (test) kernels are failing.

If I install a kernel that doesn't boot then the next kernel update will wipe out my working kernel in favor of a newer kernel that may also not work.

The simple solution would be to change the default number kept to be at least one more but this is also likely to be a problem in the case of failing test kernels.

A better solution would be to for installonlyn to only take action in the case where the currently booted kernel (via uname -r) is the latest version.
