a normal boot would have given me a busybox yes, but I added
"break=premount here", so the shell is not exactly a bug ;)
The bug is that my array was not _correctly_ assembled after running udevtrigger

Not this time, but the array was present and exiting the shell
resulted in a working boot, LVM has no problem anymore for me.

No, I copied the output to one of my boot partition, one that is _not_
in the RAID/LVM. I did it to avoir running vgscan and friends by hand
to see if the next part of the boot goes fine or not.
