otoh, all the sys parameters are in /proc/sys as well. i guess cpuinfo was
left out in the cold because its typically read-only ? but still, its not
like sysctl and proc are completely orthogonal..

DESCRIPTION
The _sysctl call reads and/or writes kernel parameters.
For example, the hostname, or the maximum number of open
files.

$ ls -l /proc/sys/kernel
total 0
-rw-r--r-- 1 root root 0 Jul 7 11:17 domainname
-rw-r--r-- 1 root root 0 Jul 7 11:17 file-max
-r--r--r-- 1 root root 0 Jul 7 11:17 file-nr
-rw-r--r-- 1 root root 0 Jul 7 11:17 hostname
