    While possible, the chmod+chown 'solutions' just aren't as simple as
    you pretend. Every time one creates a chroot environment and mounts
    /proc it has be manually fixed there as well. Same thing with a
    container. Sure if /proc were something that was only ever mounted
    one time on a box it wouldn't be so bad, but that's not the case.....
