I may have misunderstood what you're saying. But if not, you're not allowing for one using .ko's to have this functionality. How do I fail the build if I want to have 'device random' but use some external provided RNG thru a kernel module? The original changeset supported that. Or for what ever reason I want to have the choice of RNG left up to which base kernel module I load? 'sysctl kern.random.adaptors' showing an empty list does provide a bread crumb. /etc/rc.d/initrandom could certainly check this value and complain loudly. -- -- David (obrien@FreeBSD.org)
