The /sbin/functions.sh definitions file is included by the rc initscript. It performs the following series of functions:

  1. Flag RC_GOT_FUNCTIONS="yes" to avoid repetition
  2. Obtain the configuration Variables from /etc/conf.d/rc configuration file
  3. Define a series of variables
  4. Define a series of functions
  5. Run some finalization code
