-$ramdisk will fail to produce a working ramdisk, and possibly leave the system

-versions. In any case, we strongly recomend you abort here, check that
-$ramdisk does indeed support your kernel version configuration, and either

-$ramdisk should work, file a bug against the $ramdiskpackage package.
