""" 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.
