We have made a translation table of English ICT-words to Norwegian thats
easy to use if some Norwegian words has slipped through.

All the installation steps are extensively explained by Klaus Ade
Johnstad. Skolelinux is mainly made for a fully fledged computer
network at schools with heavily focused on reducing time on setup and
running a Debian system with 150 or 10000 pupils and teachers.

The hardware requirement and architecture are crucial to understand:
http://developer.skolelinux.no/~klaus/newnotater/c160.html
http://developer.skolelinux.no/arkitektur/arkitektur.html.en
It's easy to combine a thinclient server with the file server.
* To diverge from the architecture
Yes, it's possible to diverge from the architecture, use just one
network card on the server, and use dual-boot. The reason for not doing
this in i school environment is justified by the complex you get into
with manually configure the system. The teachers has not 120 hours and
time to read a 134 pages manual to to set up a server. They have 1-4
hours to maintenance in one week, and the teacher are expected to run a
computer network with 280 users and 20 teachers :-).
The Danish GnuSkole is a project that correspond to Skolelinux in
Norway. They have made a book "Linux i Skolen". It's a 134 pages thick
book on how to set up a computer network with a single server and 17
services.
http://www.gnuskole.dk/bog/
Skolelinux has taken the architecture from the computer network at the
University of Oslo, and installes many of the services, with an fully
extendable architecture. We have removed the need for reeding a 134
pages of setup and configuring manual.
We recommend to use a standard architecture when testing the system with
minimum a firewall and a test-server with single boot and two network
cards. Servers are "not made for" dual boot. The reason is that a
teacher often know witch OS he should start, or the systems starts
wrong OS by default. Dual network card is made bacause of the network
load between the thin client and the server (around 2 Mbps for every
thin client) ... We have some experience in Norway with this after done
this in the past 3 years. To sum it up:
0. Get suitable hardware if you want to test the system. If you want a
test-package, by it. The headmaster don't have the money to experiment
with hardware, or under finance the testing.

1. The hardware vendor in Norway don't sell testpackages any more.
Everybody goes for 10 thin clients with server or more. It just works.

2. A teacher have 1-4 hours a week to maintain a computer network at his
or here school. Don't introduce more workload with workarounds :-).
They just hate you, and some also switch back to their Windows 98
system, as they did in a school north in Norway.
Warning: The teacher gladly use 40 hours a week more in their spare time
to maintain a Microsoft solution if they get uncertain on some "single
user" "dual boot" oriented handling of multi user computer network
questions, independent of the OS in use . Don't go there. Use your time
on doing this right the first time by getting adequate hardware for
testing. If you have 40-80 extra hours to figure this out on your self,
it's probably OK, but not for a teacher and not for a school.
This advises are based on introducing Skolelinux to 1000 or more
ICT-responsible teachers at schools in Norway, and from experiences
from a lot of schools. Thus usability study from Statskonsult document
whats important from a user perspective:
