""" Create a new storage specification. These are used to specify
the default partitioning layout as an object before we have the
storage system up and running. The attributes are obvious
except for the following:
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.
