[one-users] NICs configuration

[Javier Fontan]

It is a problem with the configuration scripts of ttylinux. By default
it only starts 2 interfaces, even if the kernel sees more.

Form the top of my mind, this may not be totally correct:

* Go to /etc/sysconfig/network-scripts
* Copy ifup-eth0 to ifup-eth2 and change eth0 to eth2 in the script
  # sed 's/eth0/eth2/' ifup-eth0 > ifup-eth2
* Do the same for any other number of interfaces
* Delete the configuration files for interfaces generated in that
directory, I think they may be called ifcfg-eth0 and so on
* Issue a saveas for that disk
* Shutdown the vm (in the case of ttylinux and kvm you may need to
cancel it, execute sync in the vm before canceling it)

You should have a new image that supports more interfaces.
