Yes. There are no special preperations needed, it will just do it.
You can compile it under Linux or the Hurd and it will just work. Please
read the Grub documentation carefully. For a few hints, read the faq at:
http://www.debian.org/ports/hurd/hurd-faq
and the easy guide you will stumble upon if you browse the above web site.

This is for GRUB:
root= (hd0,2)
kernel= /boot/gnumach.gz root=hd0s3
Note the different numbering scheme.

Any i386 host will work for Grub.

83 is NOT linux but ext2fs, which we use.
You fdisk under Linux, create a partition up to 1 GB in size of type 0x83.
Then "mke2fs -o hurd" this partition... and follow the install instructions
at:
http://www.debian.org/ports/hurd/hurd-install

Grub can boot many OS's and chain=load all others. This is not a Hurd issue,
but a Grub issue, as Grub is the boot loader.

That's a different thing I won't explain right now.

Yes. Linux is not a micor kernel at all, so single server/multi server makes
no sense on Linux.

The oskit kernel could probably used with some porting work, I don't know.
We use GNU Mach for now.

It does not run linux programs yet. It probably will in the future simply by
linking them to a special version of the C library whicj does the emulation.
No need for seperate partitions or so.
