Comment 10 for bug 234006

Sorry, you're right. Setting the components doesn't help, you have to do something like this:

  ltsp-build-client --mirror "http://gb.archive.ubuntu.com/ubuntu" --extra-mirror "http://gb.archive.ubuntu.com/ubuntu hardy-updates main restricted"

Even more reason to at least add a simple option to enable building an image with updates. Patch attached that adds a new "--updates" option.
