Module devices

source code

Device classes for use by anaconda.

This is the hierarchy of device objects that anaconda will use for
managing storage devices in the system. These classes will
individually make use of external support modules as needed to
perform operations specific to the type of device they represent.

TODO:
    - see how to do network devices (NetworkManager may help)
      - perhaps just a wrapper here
    - document return values of all methods/functions
    - find out what other kinds of wild and crazy devices we need to
      represent here (iseries? xen? more mainframe? mac? ps?)
        - PReP
          - this is a prime candidate for a PseudoDevice
        - DASD
        - ZFCP
        - XEN

What specifications do we allow?              new        existing
    partitions

                how will we specify this?
                    partition w/ multiple parents cannot otherwise occur
