# Local device (HDD) to use as a scratch space to combine with the DNBD3 image

# This is a kind of partition table for the scratch device.
# A line is composed of:
# <type> <name> <size> <crypt>
#
# * Type can be 'thin-snapshot', 'thin-volume', 'snapshot' or 'linear'.
# * Name is just a name of the device mapper device created.
# * Size are precalculated on the writable device found, so percentages
# are calculated on the total device size. Lower and upper bounds can
# be set, these will be attributed in a first-come-first-serve manner
# (with respect to line order).
# * Crypt would encrypt the device mapper device with a temporary key.
# 0 to disable (default), 1 to enable. Currently does not support persistent
# keys.
# Example of a more advanced partition config:
# thin-snapshot root 10G 1
# thin-volume tmp 20G 0
# linear data0 5-10G 1
# linear data1 1-50% 1
# There needs to be at least one snapshot device configured, if none are set
# it will default to use the *entire* writable device as a thin-snapshot:
