# boot_hdd -- Create import/export disk images to local folder.
#
# Typically used in automation tools which run openMSX without human interaction.
# This script is basicly is a bit more generic and safe way to run the following code;
#
# diskmanipulator create disk.img 32m 32m 32m 32m
# hda disk.img
# diskmanipulator import hda1 ./disk-in/
# after quit {diskmanipulator export hda1 ./disk-out/}
#
# Supported environment variables by this script;
#
# BOOT_HDD_SIZE=30m
# Sets the size of the created partitions, defaults to 15m for dos1.
#
# BOOT_HDD_IMAGE=bin/myapp/dsk.img
# Defaults to ./hdd.dsk
#
# BOOT_HDD_PATH=bin/myapp/dsk
# provides the default values for BOOT_HDD_PATH_IMPORT and BOOT_HDD_PATH_EXPORT
#
# BOOT_HDD_PATH_IMPORT=bin/myapp/dsk
# When set enables the import of all files into the first disk partition.
#
# BOOT_HDD_PATH_EXPORT=bin/myapp/dsk-result
# When set enables the export of all files back to the filesystem
#
# BOOT_HDD_EXPORT_PARTITION=2
# When set override the export from 'first' to 'given' partition number.
#
# BOOT_HDD_EXPORT_DIR=myout
# By default export does chdir to root of msx partition override to custom export directory.
#
# BOOT_HDD_PARTITIONS=2
# The number of partitions created in the disk image, defaults to 1.
#

# per default create msxdos1 compatible partition size.
