Made a little web page:

With some remarks how I installed webpack on grml Linux.
It also holds a simple example script to configure a Digilent Digilab D2
with webpack-8.1i  without GUI.

I got a Linux distro from  www.grml.org, and have the 8.1 webpack working on
it.
This is a small distro, and I think it should be possible to make one CD
with Linux and webpack as auto-run, but I only installed on harddisk (from CD
would be too slow for me).

Interesting is that I did not get the Xilinx GUI working in the install,
likely because I changed some stuff in grml, (removed X.org x server and
changed to XFree).

I moved to grml after I got pissed at all the ever increasing bloat from
Suse10. And yes I have the Redhat fedora too as many disks, but this grml is
only one CD.

So, as all characters in the Xilinx EULA were unreadable, I figured right
click button for NO on every question, and it installed itself anyways, so I
am free of Eula ;-) Thank you X.
Anyways, I copied some libs, (all .so), to /usr/local/lib/xilinx/, added that
path to /etc/ld.so.conf, then ran ldconfig.
Did export of XILINX from the zhs shell to env, and hey I can do the whole
project from scripts. (Without GUI).
The impact did not like my X3 par port cable , downloaded 2.6 drivers from X
website, still no go.
As the digilent lab board I use here at home to test, uses a par port cable
with JTAG, started writing jtag code, then found Mr Usselman already did that
for us.
But his did not work on my system, because I did not have the par port
modules and device.
So I rewrote his program for direct IO to the parport.
You can find it here (if you use digilent digilab board):
ftp://panteltje.com/pub/p3j.c
Compile with 
 gcc -Wall -O2 -o p3j p3j.c
tested on gcc-2.95, gcc-3.3, and gcc-4.0 (yes grml has all these).
Thank you Rudolf Usselmann.

Nothing is tested very much, maybe more later.
