Looks about right, yup.

That's correct, in the same fashion that /etc/rc.conf works.

Hmm. The "right" answer would appear to be in a 'loader.rc.local', but
that's obviously not implemented at this point. The loader.rc file isn't
typically overwritten after installation, so either inserting it there or
sourcing another file at that point would be the cleanest way.

As David mentioned, Ficl isn't up and running on the Alpha yet. Daniel
Sobral was working on integrating a new version of Ficl which is meant to
be 64-bit clean.

There is some screen-handling code that is specific to the
cursor-addressable syscons emulation in the i386 loader, but I think
that's about all.
