Hi *.

I've noticed something strange.  After putting in a Cyrix NDP, and
recompiling ps and libutil.a (installing the patch for ps), ps
dies when I'm not logged in as root with

ps: kvm_openfiles: can't open /dev/mem: permission denied

The permissions on ps are:

-rwxr-xr-x ps

And the permissions on /dev/mem:
crw-r----

I haven't changed permissions on /dev/mem, and ps has worked in the past
for non-root users.

Also, why is it that when I issue ps -aux, the RSS is always 0?
