> Could a reduced kernel/image be made specifically for netboot installs?

No, not really. The "same vmlinux for installer and installed system" thing is a
relatively deeply embedded assumption (different optimisation is possible, but
the hardware support really needs to not vary too wildly), and the "same vmlinux
for netboot installs and CD-ROM installs" thing is a *very* deeply embedded
assumption.

The only way to do this, really, would be to construct a separate kernel config
which is the default installed-system config for powerpc64, and then have a more
complete config that one could install later (more kernels on the powerpc
install CD being infeasible for CD-space reasons); however I suspect without
proof that we would do that at the loss of hardware compatibility in the
installer, and that would affect CD-ROM installs too unless we do some fairly
serious reengineering which I'm loath to do.
