+=head1 NAME
+
+setup_harddisks - create partitions and filesystems on local disks
+
+=head1 SYNOPSIS
+
+ setup_harddisks [ options ]
+
+=head1 DESCRIPTION
+
+This program sets up local hard disks during the FAI installation process.
+
+The basic operation of the program is as follows:
+
+=over
+
+=item 1. B<Scan system>
+
+L<sfdisk(8)> is used to query the disks in the system. Internal lists
+are built of the discovered disks for later use. Note that there is
+no real indication about which disks are on which controllers without
+devfs.
+
+=item 2. B<Parse the config files>
+
+The config file format is detailed below in L<CONFIGURATION FILE
+FORMAT>.
+
+=item 3. B<Calculate Partition Tables>
+
+Based on the configuration file and discovered disks.
+
+=item 4. B<Write Partition Tables>
+
+L<sfdisk(8)> is used again to write tables to each disk.
+
+=item 5. B<Format Filesystems>
+
+Using any or all of:
+
+=over
+
+=item L<mke2fs(8)>, L<mkreiserfs(8)>
+
+To create filesystems on partitions
+
+=item L<mkswap(8)>
+
+To setup swap space for Linux
+
+=item L<pvcreate(8)>, L<vgcreate(8)>
+
+To set up LVM managed areas
+
+=item L<mdadm(8)>
+
+To set up Linux mdadm managed spaces.
+
+=back
+
+=item 6. B<Prepare F</etc/fstab>>
+
+The B<f>ile B<s>ystem B<tab>le is written out to F</tmp/fai> for the
+installation process to read.
+
+=item 7. B<Write out FAI variables>
+
+So that later FAI installation decisions can be made based on the
+results of this step.
+
+=back
+
+Each step is detailed more fully later in the man page.
+
+=head1 COMMAND LINE OPTIONS
+
+=over
+
+=item B<-X>
+
+With this option your hard disks will really be formatted. The
+default is to fake it.
+
+=item B<-f> I<config-filename>
+
+Specify the configuration file. The default is to parse all files
+found in the environment variable C<classes>.
+
+=item B<-c> I<class-path>
+
+Specify where configuration files live. The default is
+F<$FAI/disk_config/>.
+
+=item B<-d>
+
+Specify DOS alignment of partitions. The default is B<not> to align
+so as to suit DOS.
+
+=back
+
+=head1 CONFIGURATION FILE FORMAT
+
+FIXME - this is now a new format. This section of the documentation
+needs updating.
+
+For now, here's the EBNF grammar:
+
+ file ::= <lines> EOF
+
+ lines ::= EOL
+ /* empty lines or whitespace only */
+ | <comment> EOL
+ | <config> EOL
+
+ comment ::= #.*
+
+ config ::= disk_config lvm
+ | disk_config raid
+ | disk_config end
+ | disk_config disk[[:digit:]]+( <option>)*
+ | disk_config [^[:space:]]+( <option>)*
+ /* fully qualified device-path or short form, like hda, whereby full
+ * path is assumed to be /dev/hda */
+ | <volume>
+
+ option ::= /* empty */
+ | preserve:[[:digit:]]+(,[[:digit:]]+)*
+ /* preserve partitions */
+ | disklabel:(msdos|sun)
+ /* write a disklabel - default is msdos */
+ | bootable:[[:digit:]]
+ /* mark a partition bootable, default is / */
+ | virtual
+ /* do not assume the disk to be a physical device, use with xen */
+
+ volume ::= <type> <mountpoint> <size> <filesystem> <mount_options> <fs_options>
+ | vg <name> <size>
+ /* lvm vg */
+
+ type ::= primary
+ /* for physical disks only */
+ | logical
+ /* for physical disks only */
+ | raid[015]
+ /* raid level */
+ | [^/[:space:]]+-[^/[:space:]]+
+ /* lvm logical volume: vg name and lv name*/
+
+ mountpoint ::= -
+ /* do not mount */
+ | swap
+ /* swap space */
+ | /[^[:space:]]*
+ /* fully qualified path */
+
+ name ::= [^/[:space:]]+
+ /* lvm volume group name */
+
+ size ::= [[:digit:]]+%?(-[[:digit:]]+%?)?(:resize)?
+ /* size in megabytes or %, possibly given as a range; physical
+ * partitions or lvm logical volumes only */
+ | -[[:digit:]]+%?(:resize)?
+ /* size in megabytes or % given as upper limit; physical partitions
+ * or lvm logical volumes only */
+ | preserve[[:digit:]]+
+ /* do not modify this partition */
+ | [^,:[:space:]]+(:(spare|missing))*(,[^,:[:space:]]+(:(spare|missing))*)*
+ /* devices and options for a raid or lvm vg */
+
+ mount_options ::= [^[:space:]]+
+
+ filesystem ::= -
+ | swap
+ | [^[:space:]]
+ /* mkfs.xxx must exist */
+
+ fs_options ::= .*
+ /* options appended to mkfs.xxx call */
+
+=over
+
+=item B<disk_config> [ I<device> | B<end> ]
+
+The disk_config command must precede each disk's partitioning
+information.
+
+I<device> is the harddisk to format, with "/dev" removed. For
+instance, "hda" or "sdc".
+
+If the special keyword B<end> is used, parsing of the configration
+file halts.
+
+=item B<disk_reserve> [ I<SIZE> ( I<unit> ) ]
+
+Specify that some of this disk should not be allocated to any
+partition. I<unit> can be C<G>, C<M> (the default), or C<%>
+(specifying a percentage). This is always rounded down to the nearest
+cylinder.
+
+This is primarily useful where you can't be sure to get the same disk
+model as a replacement for a RAID array. It might be slightly
+smaller, so here you get to specify the trade-off between less disk
+space and less likelihood of a disk replacement not able to be added
+to your RAID array.
+
+=item B<primary> | B<logical> ...
+
+B<primary> and B<logical> define partitions.
+
+The syntax is:
+
+ type mountpoint size fstab-options ; extra options
+
+=over
+
+=item B<type>
+
+This may be C<primary> or C<logical>.
+
+B<primary> paritions are those created within a normal DOS-style
+partition table (eg, F</dev/hda1> through F</dev/hda4>).
+
+B<logical> partitions are created inside the last (by convention)
+primary partition (eg, F</dev/hda5> and above).
+
+Only primary partitions are bootable by boot loaders like GRUB and
+LILO.
+
+=item B<mountpoint>
+
+This is the name of the entity that this partition is allocated to.
+
+B<Normal partitions> are defined with the name of the mount point,
+such as C</>, C</usr>, C</var>, C</home>, etc.
+
+To use a partition as a B<swap device>, use the special value C<swap>.
+
+If it is set to C<->, to the partition will be B<unused>.
+
+=item B<size>
+
+The size of the partition.
+
+To specify an B<exact size>, list a number in mebibytes (MiB, 1024 *
+1024 bytes), such as C<30> for 30MiB.
+
+To specify a B<range>, use the hyphen (C<->), such as:
+
+=over
+
+=item 10-100
+
+10 to 100MiB
+
+=item 20-
+
+At least 20 mebibytes
+
+=item -500
+
+up to 500 mebibytes.
+
+=back
+
+Partition sizes will be rounded up to the next cylinder boundary.
+
+=back
+
+To specify a partition should B<remain untouched>, use the syntax
+C<preserve>I<num>. For example, C<preserve3> for the existing third
+partition on the disk.
+
+If the I<device> was C<hda> then this results in C<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. Logical
+Partitions can not currently be preserved. The I<bootable> flag will
+not be preserved. Preserved partitions are mounted read-only during
+installation.
+
+=item B<fstab-options>
+
+These options are copied to the fourth column of the F</etc/fstab>,
+and specifies I<mount options>. See L<fstab(5)> for more information
+on mount options. The default is C<defaults>.
+
+=item B<extra options>
+
+Extra options are specified after the semicolon, should be seperated
+by a comma, and include:
+
+=over
+
+=item B<format>
+
+Always format this partition, even if C<preserve>I<N> was specified.
+
+=item B<ext2>
+
+Format the filesystem as ext2 (this is the default)
+
+=item B<-j> or B<ext3>
+
+Format the filesystem as ext3
+
+=item B<-i> I<bytes>
+
+Bytes per inode (only ext2/3 filesystem)
+
+=item B<-m> I<blocks>
+
+Reserved block percentage for super-user (only ext2/3 filesystem)
+
+=item B<reiser>
+
+Format the filesystem as ReiserFS, using L<mkreiserfs(8)>.
+
+=item B<-h> I<hash>
+
+If formatting a ReiserFS filesystem, set the `hash' algorithm.
+
+=item B<-v> I<ver>
+
+If formatting a ReiserFS filesystem, set the reiserfs version.
+
+=item B<dosfat16>
+
+Format the filesystem using FAT16 (baby's first filesystem), as used
+by DOS 2.0 and above.
+
+=item B<winfat32>
+
+Format the filesystem using FAT32 (bloated baby's first filesystem),
+as used by Windows 95 and above.
+
+=item B<lazyformat>
+
+Do not format if partition has not moved (useful for testing the
+installation)
+
+=item B<boot>
+
+Make this (primary) partition as bootable (by default, only the linux
+root filesystem is marked as bootable).
+
+=item B<writable>
+
+Mounts a preserved partition in read-write mode
+
+=item B<raid(>I<X>, B<md>I<N>[I<a>][, I<F>]B<)>
+
+Set up the partition as part of a RAID set.
+
+I<X> specifies the RAID level - 0 means striping, 1 mirroring and 5
+cursing.
+
+I<N> specifies the number of the RAID set - ie, C</dev/mdI<N>>.
+
+I<a> specifies which half of a mirror a volume in a RAID 10 set is.
+This may be a letter from C<a> to C<e>, allowing up to 5 halves to
+your mirror.
+
+I<F> specifies the chunk factor. This is the same as you would
+specify it to the kernel on the command line and represents
+log(chunk_size_in_KB)/log(2) - 12. See L<BASIC MATH> for more. The
+default is 8.
+
+=item B<lvm>[(I<VGname>)]
+
+Set up the partition as a physical volume in a volume group.
