	5	1. FORMAT OF THE RECIPE FILES
	6	-----------------------------
	7
	8	All new lines and tabulations in the recipe are converted to spaces.
	9	Then two or more consequtive spaces are converted to one space.
	10	Almost all tokens must be separated by spaces. An important exception
	11	is the opening curly bracket ("{"), before it there must be _no_
	12	space.
	13
	14	In the following rules we denote spaces by "_".
	15
	16	<recipe>::=<header>_<partitions>
	17
	18	<header>::=<simple name>\|<debconf name>
	19
	20	<simple name>::=<name>_:
	21
	22	<name> can be for example "Multi user system".
	23
	24	<debconf name>::=<debconf template>_::
	25
	26	The purpose of <debconf name> is to allow translation of the names of
	27	the recipes into different languages.
	28
	29	<partitions>::=<partition>\|<partition>_<partitions>
	30
	31	<partition>::=<limits>_<specifiers>_.
	32
	33	<limits>::=<minimal size>_<priority>_<maximal size>_<parted fs>
	34
	35	<minimal size> is the minimal allowed size of the partition in
	36	megabytes. It is rounded to cylinder size, so if you make <minimal
	37	size> to be 20 MB and the cylinder size is 12MB, then it is possible
	38	for the partition to be only 12MB.
	39
	40	<maximal size> is the maximal size for the partition, i.e. a limit
	41	size such that there is no sence to make this partition larger.
	42
	43	<priority> is some size usually between <minimal size> and <maximal
	44	size>. It determines the priority of this partition in the contest
	45	with the other partitions for size. Notice that if <priority> is too
	46	small (relatively the priority of the other partitions) then this
	47	partition will have size close to <minimal size>. That's why to small
	48	partitions it is recomented to give <priority> larger than their
	49	<maximal size>.
	50
	51	<parted fs> is the file system as known to parted of this partition.
	52
	53
	54	<specifiers>::=<specifier>\|<specifier>_<specifiers>
	55
	56	<specifier>::=<internal specifier>\|<regular specifier>
	57
	58	<internal specifier>::=$primary{_}\|$bootable{_}
	59
	60	$primary{_} says that the partition should be primary (if possible).
	61	$bootable{_} says that the bootable flag will be set.
	62
	63	<regular specifier>::=<file name>{ <file contents> }
	64
	65	<file name> is a file to be created in the directory of the partition.
	66	<file contents> is the information to write in this file.
	67
	68
	69	2. ARCHITECTURE DEPENTENT RECIPES
	70	---------------------------------
	71
	72	Some architectures have specific requirements for their partitions.
	73	For example many of them require special partitions to support
	74	bootloading.
	75
	76	Suppose that the architecture is powerpc/powermac_newworld. Then
	77	partman-auto will look in the following places for recipes:
	78
	79	/lib/partman/recipes-powerpc-powermac_newworld/*
	80	/lib/partman/recipes-powerpc/*
	81	/lib/partman/recipes/*
	82
	83	Partman-auto will use the recipes from the first of these directories
	84	that exists.
	85
	86	Due to limitation of the algorithms in partman-auto, there must be at
	87	least one partition with high maximal size so that the whole free
	88	space can be used. Usualy you can give the partition containing /home
	89	a maximal size 1000000000 which is high enouhg for the present storage
	90	devices. Do not use higher than 1000000000 numbers because the shell
	91	arithmetic is limited to 31 bits (on i386).

	1
	2	* Anton Zinoviev
	3	- move the item in the main partitioning menu up.
	4	- recipes/multi_user: give higher priority to the size of /tmp, the
	5	limits are still the same (min = about 20MB, max = about 400MB).
	6	Thanks to Ivan Nestlerode, closes: #246749
	7	- recipes.sh (choose_recipe): add support for architecture dependent
	8	recipes
	9	- add recipes customised for powerpc newworld. Thanks to Brett Wuth,
	10	Giuseppe Sacco, Jared Sulem and Dave Miller,
	11	closes: #241817, #244957, #243253, #244977
	12	- add recipes customised for hppa
