Hello Matthias,

hm, the systctls are present on my 64 bit testing machine:

> [root(a)maverick ~]# sysctl -p
> - snip -
> vm.mmap_rnd_bits = 32
> vm.mmap_rnd_compat_bits = 16
> - snip -
> [root(a)maverick ~]# arch
> x86_64

Unfortunately I do not have 32 bit hardware at hand, and
the absence of those parameters surprises me.

@All: Does anybody have access to something more uncommon
like ARM SOCs? What about those?

@All, second: Does it make sense to ship different sysctl
values for different platforms?

Sorry for the inconvenience.

Thanks, and best regards,
Peter Müller
