Sort of. The pre generated images that we ship have "generic"
initramfs which have a LOT of drivers so the images will boot on the
vast majority of Arm devices, once the first kernel update is applied
it automatically moves to a host specific initramfs so will then be a
lot smaller, and hence much quicker to boot, but will not be a generic
initramfs.
Excellent! That is a good design.
