Looking closer, the CONFIG option keeps non-heap address-space

Set it, as root, via

Off topic, but do you need the -n flag? I always just "echo num >
/proc/sys/path" and I've never had a problem, but is there a case
where it matters?
No you don't in fact need it for sysctls -- the first newline is
simply ignored (as is all other trailing whitespace by the way).
When you echo things into /sys (a device id into a driver "bind"
attribute for example) that's not always the case though and my "-n"
came about sort of automatically.
The "proper" way of setting sysctl's is in fact though the sysctl
program:
# sysctl kernel.randomize_va_space=0
but hey...
Rene.
Actually, I think sysctl is deprecated and on its way out. I'd better
double check that. I think the general consensus was that there was no
need for it since you can just echo in arguments. Maybe Red Hat is
deprecating it and I'm thinking it's everyone. I'll get back to you
guys on this in a few hours.
