It doesn’t need to get built, as its already in the store.

Though it wouldn’t needed anyway, as the activation doesn’t magically swap out the activev kernel.

It reuses the kernel of the currently running system generation and tries to apply as much as possible of the rest of the generation on top of the things it can not change.

FWIW, there seems to be a `configurationLimit` option for other bootloaders, including grub and raspberry Pi, too. Cool.
