# This program first read the configfiles, partitions and formats the harddisks,

# Parameters:
# [-X] no test, your harddisks will be formated
# default: only test, no real formating
# [-f<config-filename>] default: parse classes
# [-c<class-path>] default: $FAI/disk_config/
# [-d] default: no DOS alignment

#
# config-file format:
# lines beginning with # are comments
#
# "disk_config <device>|<diskN>|end"
# The disk_config command starts the parsing.
# It has to be the first command.
# <device> is the harddisk to format in short form like "hda" or "sdc".
# <diskN> if first is used, the N-th disk of $disklist is used
# "end" = end parsing here
# Example: "disk_config hdb"
# Example: "disk_config disk3"
#
# Defining one partition:
# "primary|logical mountpoint|swap|- <size in mb>|preserve<No> [fstab-options][;extraordinary options]"
# "primary|logical":
# "primary": this are the bootable partitions like the
# root directory "/" or the DOS "C:" disk.
# "logical": this are all other partitions like a linux
# "/var" or a swap partition or a DOS disk.
#
# "mountpoint|swap|-":
# "mountpoint":
# This is the mount-point for fstab.
# For example "/","/var","/usr". There must not
# be a space in the mountpoint.
# "swap":
# swap-partitions
# "-":
# do not mount this partition.
#
# "<size in mb>|preserve<No>":
# "<size in mb>":
# The size of the partition in megabyte
# Examples:
# "30" = 30 mb
# "10-100" = 10 to 100 mb
# "20-" = minimum of 20 mb
# "-500" = 1 to 500 mb
# The megabytes will be rounded up to cylinders.
# "preserve<No>":
# This is the alternative for the size attribute.
# <No> is the partition number. For example
# preserve3 for the third partition. If the
# <device> was hda then this results in hda3.
# The partition will be left unchanged. This
# is useful if you have partitions that do not
# need re-installation or if you want to have
# other operation systems on the device together
# with Linux. Extended Partitions can not be preserved.
# The bootable flag will not be preserved.
# Preserved partitions are mounted readonly during
# installation.
#
# "fstab-options":
# These options are copied to the fstab-file. The
# default is "default"
#
# After the semicolon there could be extra options like:
# -i <bytes> : Bytes per inodes
# (only ext2/3 filesystem)
# -m <blocks>% : reserved blocks percentage for superuser
# (only ext2/3 filesystem)
# -j : format in ext3
# -c : check for bad blocks
# format : Always format this partition even if preserve
# lazyformat : Do not format if partition has not moved
# (useful for testing the installation)
# boot : make this partition the boot-partition (the
# linux root filesystem is the default)
# ext2 : Extended 2 filesystem (this is the default)
# swap : swap partition
# dosfat16 : DOS 16bit FAT file system
# winfat32 : Win95 FAT32 file system
# writable : mounts a preserved partition writable
# xfs : xfs
# reiser : reiserfs
# -h <hash> : set reiserfs hash
# -v <ver> : set reiserfs version
