the default partitioning layout as an object before we have the

storage system up and running. The attributes are obvious

|
|
|
||
|
|
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.
