Yet I see no thought whether having the scheduler see sched_clock()
suddenly change is a good idea or not. The point of the initialisation
being early is to avoid a jump in the scheduler clock.

So, was the commit you're trying to fix a good idea after all?

That question at least needs to be considered, rather than just moving
stuff like this later.
