howto make devices in the /dev dir

[Jerôme Magnin <jerome.magnin@neurocom.com>]

I wish I knew how to create devices for my HDD and my different
partitions ... so I could declare a device for my swap partition ...
I was able to declare the cdrom, but I m afraid of breaking my other
system which is on the same HDD, while declaring the devices for this
HDD

for info: my HDD is an IDE disk, which is master on the first IDE bus
...
the partition for the HURD is hd0s7, my swap is (will be) hd0s2...

Other question: can I use my Linux binaries with the hurd??
