Would that mean having one preserved image per machine, or could I have one
image, download it to all machines and then automagically set hostname/IP
address by referencing the MAC address somehow? Is their best practice for
this sort of shennanigans?

Cheers Alex, these look really good. I particularly like the look of
Mindi/Mondo. My machines don't have CD-Rs in, but I may be able write an
image to hard disk and then send it to a machine with a CD-R... if the
resulting CD(s) are bootable then Bob is very much my uncle, although I'll
still want a natty way of assigning hostname/IP address as above.

Thanks for the help, excellent food for thought!

Thanks Steve, it does look impressive. I wonder how it will perform on a bus
network? I'm sure it would still work, but I wonder if the switched ethernet
functionality is key to its performance? Oh well, one way to find out...

Well, the machines are all identical, so no problems there, but I'm not sure
I quite get your method; I thought PXES was a thin client/X-client jobber...
ok so that gets my boxes up and running, but how do I do the "NFS mount
re-install"? More to the point, can I automate it/do it unattended?

Sorry if I am being dense!

First of all, using DHCP, you can statically assign an IP address to a
given MAC address (which is also the best way to handle servers which
should remain on a fixed IP address) in a DHCP environment.

Secondly, Kickstart works by having configuration file for each IP address
(or MAC address - I can't remember which, but it doesn't really matter, as
above) and a single unified source of Red Hat installation images
available via NFS, FTP or, I think, SMB.

Kickstart is probably most useful in labs or "enterprise" workstation
environments.
