    Sometimes you  can't use partman-auto.  Sometimes you have to
    perform your own partition management.  This doesn't solve your
    problem, but does show how an example customized partitioning scheme
    might be configured.  This scheme does away with a swap partition.

    There are many example schemes you can find with a search.
