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.
