The second method requires to introduce the kern.arnd sysctl

I don't see any problem with introducing such a sysctl, if it would make
the propolice patch simpler.
Thanks for you answer. In that case, which sysctl should we use ?
* OpenBSD's kern.arnd (KERN_ARND) which is a front-end to
the arc4random() function ?
* NetBSD's kern.urandom (KERN_URND) which is using the rnd(4)
pseudo-device. They also have KERN_ARND in sysctl.h, which
is no more than a #define of KERN_URND, for compatibility
with OpenBSD.
Usually, I noticed that FreeBSD used to be as close as possible with
NetBSD. But I would like to hear the voice of a more experienced
hacker about this.
I asked a certain person to add the obsd sysctl long ago but it never
happened.
