Ubuntu ships different kernels for desktop and server usage. From a
packaging standpoint it would be much nicer to have this set in the
kernel configuration. If we were to throw the setting /etc/sysctl.conf
the kernel would depend upon the package containing sysctl(8)
(procps). We'd rather avoid this and keep the default kernel
configuration in one place. This was just an RFC though; let me know if
you think this is totally insane.
