I'm pretty sure that overriding internal network functions in this 
configuration file isn't supported either by RHEL or augeas. Have a look 
in /usr/share/doc/initscripts-*/sysconfig.txt for supported directives.

I think parsing this in any useful way would be extremely difficult. The 
author of this change has decided to go beyond the supported syntax to 
use arbitrary shell syntax. Parsing that is a daunting prospect to say 
the least :)
