as legal has said we cannot pregenerate initramfses i think this should
be a non-starter. even loading a 20mb initramfs from a sdcard on a slow
arm box doesnt take that long, and id personally much rather be able to
change hardware or yank the drive  and put it into a different box
without worrying about making sure i have the right initramfs bits in
place. at least to me the costs outweigh the benefits. the grub timeout
on my laptop/desktops is longer than the time it takes to load the
initramfs.
