Not that I'm aware of, other than the source itself.

Not that I am aware of.

What I've seen most people doing is using the post-install features to
call a script after everything else is done.  Unfortunately, this
doesn't give you scriptable control over the NIC used.

I pregenerate an appropriate install.cfg based on system type, and
then create a DHCP group (I use isc-dhcpd) for all MACs of that type.
 I associate that group with a slightly different nfsroot (containing
the appropriate config file) for that family of machine.  It's not
pretty, but it works.

I found this post by Ceri Davies to be helpful:
