it would be nice if the lack of this file wasn't a major problem
and that, eg, if rdrand was available it would be used as a seed
instead/additionally

the two cases i see this regularly are pxe booted systems and in
the installer, both a fairly important cases so i think supporting
them as well would be worthwhile.
