This directory contains settings similar to those found in /etc/sysctl.conf.
In general, files in the 10-*.conf range come from the procps package and
serve as system defaults. Other packages install their files in the
30-*.conf range, to override system defaults. End-users can use 60-*.conf
and above, or use /etc/sysctl.conf directly, which overrides anything in
this directory.

After making any changes, please run "invoke-rc.d procps start".
afrodeity@afrodeity-desktop:~$ sudo invoke-rc.d procps start

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service procps start

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start procps
procps stop/waiting
