Yes, it's been pushed. Sorry about this. I am a little concerned that
loading bpf rc keymaps from udevd is not the best idea. Possibly this should
be done via polkit. These changes seem a little fragile and as this shows,
if it goes wrong then you end up with a system that doesn't boot...

Thanks for your report/test, making a quick turnaround for a fix possible.
