Please go implement the placing of the version that is used to cause uname -U to output 1200086 or whatever from /usr/sbin/uname at build time, which is not an issue at all as far as reproducabile builds as that version number is the same no mater how many times you run the build. This is the current defining value that says your kernel is compatible with userland and should also be the defining value for if your boot code is also compatible.
