I'm also in favor of it.  But what I need are volunteers.  Or else it
won't get done.

Someone would have to try to hack in grub support for bf (perhaps use
a top-level config switch), but not enable that by default for a bit,
so we can assess how well this works.

Although thinking about it, we could get use grub for CD booting without
in fact using grub when we're installing the new MBR on the system,
couldn't we?  Aren't these different issues?

I agree. It's a pain in the butt to keep reminding users about the
various kernel flavors.  Most just boot off CD 1 and have done with

Furthermore, you have to then swap CDs anyhow to get the kernels and
base and such.  Our system of multiple CD booting is a complete hack
and I would love to do away with it for woody.

That is kinda a frill, isn't it?

I think it's a syslinux thing, not a lilo thing, though.

But, if we're using grub for CD booting, couldn't we eliminate
syslinux also?

I need to get more educated on grub.  So little time...
