what are the *required* variables for defining a new distro?

[Robert P. J. Day]

  i asked about this on OE list but since this affects the yocto dev
manual, i thought i'd ask here as well as i can fold the result into
another doc patch.

  section 5.10 of dev manual:

http://www.yoctoproject.org/docs/latest/dev-manual/dev-manual.html#creating-your-own-distribution

claims:

  Your [new distro] configuration file needs to set the following
required variables:

     DISTRO_NAME
     DISTRO_VERSION

  i don't think that's true -- i don't think it's *required* for a
distro conf file to set DISTRO_NAME. can someone verify what variables
are mandatory for a new distro configuration file?

The bottom line is, if you mean "which variables must I set in my distro config 
or my build will blow up?" - there aren't any; we already have reasonable 
defaults for all of the critical stuff, so the distro config mostly only needs 
to change the things you want to be different. DISTRO_NAME and DISTRO_VERSION 
are the minimum of variables that you'd *want* to set, though.

Cheers,
Paul
