Would have been, or would be nice if they could make an alias to 'the first Ethernet controller' (i.e. eth0). So that you could reference it in such a way when there is only a single Ethernet controller in a machine.

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.
