Comment 9 for bug 234006

just on a sidenote: that would have to be ltsp-server (which sets the options and creates teh sources.list of the client)
but as stephane already pointed out, it's a non trivial change to add another pocket vs adding a component. one possible fix would be to set ---copy-sourceslist by default and rely on the fact that the server has $release-updates enabled properly ... so the servers sources.list ends up in the client env.
