Calculate the layout of the partition table. Partition sizes
are defined as percentage values or a tuple of percentage and
partition type.
For example:
[ 33, [66: 82] ]
Defines the first partition to be a size of 1/3 the disk,
while the remaining 2/3's will be of type Linux Swap.

Parameters:
definition: dictionary describing how to create the partition.
The following are supported values in the dict:
overwrite: Should the partition table be created regardless
of any pre-existing data?
layout: the layout of the partition table
table_type: Which partition table to use, defaults to MBR
device: the device to work on.

Create a file system on the device.
label: defines the label to use on the device
fs_cfg: defines how the filesystem is to look
The following values are required generally:
device: which device or cloud defined default_device
filesystem: which file system type
overwrite: indiscriminately create the file system
partition: when device does not define a partition,
setting this to a number will mean
device + partition. When set to 'auto', the
first free device or the first device which
matches both label and type will be used.
'any' means the first filesystem that matches
on the device.
When 'cmd' is provided then no other parameter is required.
