It gets sourced in the pre-start script, which already has to be a script.
Using this file for gssd options would require spawning another subshell in
place of the 'exec', which is what we want to avoid.

Title:
  nfs-common: gssd upstart config does not permit usage of startup
  options

Status in “nfs-utils” package in Ubuntu:
  Won't Fix

Bug description:
  Ubuntu Version: Quantal
  Package: nfs-common
  Version: 1:1.2.6-3ubuntu2

  Problem:
  The upstart init config for gssd does not permit any command line options to gssd. There are however some very important options for gssd which should be configurable in /etc/default/nfs-common, using a variable RPCGSSDOPTS.

  The following trivial patch fixes the problem:
