Only create "host-only" initramfs images. A generic fallback image
should be installed by anaconda on installation/update and never ever
be removed.
== Detailed description ==
Current initramfs images contain most of the kernel drivers to boot
from any hardware. This results in a very big initramfs, which takes
a long time to load on system start and a long time to create on
kernel updates. Switching to host-only will improve the situation. To
cope with hardware change, a boot entry "Rescue System" should be
installed with a full fledged initramfs also containing debug tools.
This boot entry can then be used to recover from hardware changes and
also from unforseen software failure after updates.
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.
