The ifcfg-rh plugin attempts to interpret ifcfg files just like
ifup/ifdown do.  These limitations and extensions should be documented
better.  But in the end, you want better documentation for the ifcfg
file format as defined by Red Hat/Fedora (SUSE's is slightly different).
Most of that has been documented since the beginning of time in places
like:

ifup-ipv6
ifup-wireless
man ifup
/usr/share/doc/initscripts-*/sysconfig.txt

But of course some of that is out of date, and NM implements WPA and
802.1x support that the system initscripts don't.  Better documentation
all around?
