I think the best place to start is debootstrap. As AJ Towns said in the
bts, the current patch is unacceptable for debian.

It looks like I am too late to be commenting :)

Cross installing from GNU/Linux should be the same as installing
a neighbourhurd. So, yes, this is very much of interest to anyone
working with the Hurd.

Do do the stuff above you need to run Bochs, or other type of
emulator/virtualizer.

For Debian GNU/Hurd, the installation should be almost the exact same
as for Debian GNU/Linux, as this is the Debian installer.

I'm not sure, I haven't looked at Wolfgang's init system yet. It
might be nice to use it.

Hopefully the differences will be abstracted out by the Debian installed.

As long as the debian packages have some abstract way of affecting the
system initialization, we can do whatever we want.

Some comments on debootstrap. I looked at it over the weekend. I'm about
half done the work, and none of the testing (the long part). So, I'll try
to unbreak my GNU/Hurd box at home and fix this stuff up in the comming
weekend.
After debootstrap, hopefully someone can look at debian-installer and see
what we can get from it or we can do for it, as I should say.
