It works! Great job, Rafael.

For everyone else, I've been bugging Rafael about this for a few months;
urpmi parallel mode is now a good deal more useful for small home
networks. If you're like me and you have two or three machines on your
local network that you have running Cooker, try it out, it's a lot more
convenient, quicker and more conservative with bandwidth than updating
each machine individually (or keeping a full Cooker mirror on your main
machine, or whatever). Install the latest urpmi on all machines first.
Then on the machine you want to be the host, install urpmi-parallel-ssh.
Edit /etc/urpmi/parallel.cfg (create it if non-existent) to look like
this:

local:ssh:localhost:toy:htpc

Where 'local' is an arbitrary name to refer to this group of machines
(pick any name you like), and localhost:toy:htpc is the list of
hostnames you want to update (unlimited, : separator). Install 'fanout'
on the host machine. Now do this:

# fanout "hostname1 hostname2 localhost" "urpmi.update -a"
# urpmi -v --parallel --auto-select

urpmi on the host machine will ask each machine in the group which
packages it needs to update, go out and grab all the packages,
distribute them via scp to each machine, then have each machine update
itself. The recent change is that having the host machine in the
parallel group now works (i.e. having 'localhost'
in /etc/urpmi/parallel.cfg) - previously, urpmi would trip over its own
lock files, but rafael's fixed this.

I'm not sure the 'fanout' stage is necessary, I think each machine goes
off the hdlists on the host machine, but I do it just to make sure each
machine has its hdlists up to date if I want to urpmi something on the
machine individually.
