note: DO NOT DO THIS ON A PRODUCTION SYSTEM. last week i was running an unsigned kernel and went to upgrade it to a signed version and it came back with asking me about removing a running kernel. in recent times that hasn't been and issue so i aborted the install and then downloaded the desired kernel and installed it by hand myself. in the process of doing that i screwed up a few links but was able to recover since i had a bootable stable partition.
i eventually got the unsigned kernel version removed and replaced by the desired signed version. todays upgrade went smoothlyy as expected. the question is for someone who has a system they're willing to play with and see if you can replicated my problem or not as i'd like to file a bug if there is indeed a problem. songbird
