Added support for Ubuntu which uses the 'procps' service provided by the 'procps' package and controlled via 'upstart'.
Converted tabs to whitespaces and fixed messed up indentation.
Aligned assignments for better readability.
Changed 'exclusive' to default to 'false' instead of 'true' to prevent accidentally nuking all default sysctl values as provided by the distribution.
Merge branch 'beautification'
Merge branch 'non-exclusive-default'
