[Setools] Separate demo box for Gjallar

[goran at krampe.se]

Hi!

Ok, I played around last night with dynamic DNS and managed to get it to
work (it was easy) so that my Ultra 5 up in the attic renews a DNS entry
for itself every 10 minutes. This means that we can use it as a Gjallar
demo box, it runs Debian.

And if it turns out to be too slow - I have another box that is faster
that we can use. Just wanted to mention that I am working on it. :)

regards, Göran
