Installer seems to overwrite partition table

[Matthew Dillon]

    I think to do this properly we need to augment the installer in a
    non-trivial way by having it detect whether the current partition
    table is using wrapped values or not, make the detected mode the default,
    but also let the user change it before completing that step.

    Detection of wrapped mode could be added to fdisk fairly easily. 
    The installer work would probably take a day.  I've got my hands full,
    I can't do it, so we need a volunteer.

    Dave Hayes has done all the hard work of bringing the installer into
    our CVS tree so it's all right there in /usr/src/usr.sbin/installer.
