Our diskless setup has become overly convoluted -- I still use the simple
Sun-style.  That said /etc/defaults/rc.conf is populated by 'make
installworld'.  We have a published interface (entropy_file="/entropy" #
Set to NO to disable caching entropy through reboots), and
'rc.d/preseedrandom' should be made to properly use it.

If some diskless environments are too broken to allow the published
interface, why can't hacks for them be added to 'rc.d/initdiskless'?
