+ asVol -- Should this be allocated as a logical volume? If not,
+ it will be allocated as a partition.
+ weight -- An integer that modifies the sort algorithm for partition
+ requests. A larger value means the partition will end up
+ closer to the front of the disk. This is mainly used to
+ make sure /boot ends up in front, and any special (PReP,
+ appleboot, etc.) partitions end up in front of /boot.
+ This value means nothing if asVol=False.
+ requiredSpace -- This value is only taken into account if
+ asVol=True, and specifies the size in MB that the
+ containing VG must be for this PartSpec to even
+ get used. The VG's size is calculated before any
+ other LVs are created inside it. If not enough
+ space exists, this PartSpec will never get turned
+ into an LV.
