I thought it might just be a first example and that debootstrap
(installed last night) would be used to set up the real container.

Anyway the name is simply the directory name in /var/lib/container
so changing it is easy. (But better power off the container first.)

I've added 195.160.172.51.

The 195.160. IPs are obviously only valid at CCCB. Maybe it's better
to set them in a file in /srv/35c3/etc/network/interfaces.d/ instead
of /etc/network/interfaces as I did?

Yes, sorry, I forgot about that in the kernel config.

I've added SCTP (the kernel tree is under /root/ - run make then lilo)
and rebooted - it looks good.
