manual: use one-line titles instead of two-line titles (trivial)
Asciidoc supports two syntaxes for section titles: two-line titles (title
plus underline consisting of a particular symbol), and one-line titles
(title prefixed with a specific number of = signs).
The two-line title underlines are:
Level 0 (top level): ======================
Level 1: ----------------------
Level 2: ~~~~~~~~~~~~~~~~~~~~~~
Level 3: ^^^^^^^^^^^^^^^^^^^^^^
Level 4 (bottom level): ++++++++++++++++++++++
and the one-line title prefixes:
= Document Title (level 0) =
== Section title (level 1) ==
=== Section title (level 2) ===
==== Section title (level 3) ====
===== Section title (level 4) =====
The buildroot manual is currenly using the two-line titles, but this has
multiple disadvantages:
- asciidoc also uses some of the underline symbols for other purposes (like
preformatted code, example blocks, ...), which makes it difficult to do
mass replacements, such as a planned follow-up patch that needs to move
all sections one level down.
- it is difficult to remember which level a given underline symbol (=-~^+)
corresponds to, while counting = signs is easy.
This patch changes all two-level titles to one-level titles in the manual.
The bulk of the change was done with the following Python script, except for
the level 1 titles (-----) as these underlines are also used for literal
code blocks.
This patch only changes the titles, no other changes. In
adding-packages-directory.txt, I did add missing newlines between some
titles and their content.

# Level 0 (top level): ====================== =

# Level 2: ~~~~~~~~~~~~~~~~~~~~~~ ===

pattern = re.compile(r'(.+\n)\%s{2,}\n' % symbol, re.MULTILINE)

new = s
new = replace_title(new, '=', '=')
new = replace_title(new, '+', '=====')
new = replace_title(new, '^', '====')

== Makeuser syntax documentation
|
2013-04-12 09:14:18 +02:00
|
|
|
|
|
|
|
|
The syntax to create users is inspired by the makedev syntax, above, but
|
|
|
|
|
is specific to Buildroot.
|
|
|
|
|
|
|
|
|
|
The syntax for adding a user is a space-separated list of fields, one
|
|
|
|
|
user per line; the fields are:
|
|
|
|
|
|
|
|
|
|
|=================================================================
|
|
|
|
|
|username |uid |group |gid |password |home |shell |groups |comment
|
|
|
|
|
|=================================================================
|
|
|
|
|
|
|
|
|
|
Where:
|
|
|
|
|
|
|
|
|
|
- +username+ is the desired user name (aka login name) for the user.
|
|
|
|
|
It can not be +root+, and must be unique.
|
|
|
|
|
- +uid+ is the desired UID for the user. It must be unique, and not
|
|
|
|
|
+0+. If set to +-1+, then a unique UID will be computed by Buildroot
|
|
|
|
|
in the range [1000...1999]
|
|
|
|
|
- +group+ is the desired name for the user's main group. It can not
|
|
|
|
|
be +root+. If the group does not exist, it will be created.
|
|
|
|
|
- +gid+ is the desired GID for the user's main group. It must be unique,
|
|
|
|
|
and not +0+. If set to +-1+, and the group does not already exist, then
|
|
|
|
|
a unique GID will be computed by Buildroot in the range [1000..1999]
|
|
|
|
|
- +password+ is the crypt(3)-encoded password. If prefixed with +!+,
|
|
|
|
|
then login is disabled. If prefixed with +=+, then it is interpreted
|
|
|
|
|
as clear-text, and will be crypt-encoded (using MD5). If prefixed with
|
|
|
|
|
+!=+, then the password will be crypt-encoded (using MD5) and login
|
|
|
|
|
will be disabled. If set to +*+, then login is not allowed.
|
|
|
|
|
- +home+ is the desired home directory for the user. If set to '-', no
|
|
|
|
|
home directory will be created, and the user's home will be +/+.
|
|
|
|
|
Explicitly setting +home+ to +/+ is not allowed.
|
|
|
|
|
- +shell+ is the desired shell for the user. If set to +-+, then
|
|
|
|
|
+/bin/false+ is set as the user's shell.
|
|
|
|
|
- +groups+ is the comma-separated list of additional groups the user
|
|
|
|
|
should be part of. If set to +-+, then the user will be a member of
|
|
|
|
|
no additional group. Missing groups will be created with an arbitrary
|
|
|
|
|
+gid+.
|
|
|
|
|
- +comment+ (aka https://en.wikipedia.org/wiki/Gecos_field[GECOS]
|
|
|
|
|
field) is an almost-free-form text.
|
|
|
|
|
|
|
|
|
|
There are a few restrictions on the content of each field:
|
|
|
|
|
|
|
|
|
|
* except for +comment+, all fields are mandatory.
|
|
|
|
|
* except for +comment+, fields may not contain spaces.
|
|
|
|
|
* no field may contain a colon (+:+).
|
|
|
|
|
|
|
|
|
|
If +home+ is not +-+, then the home directory, and all files below,
|
|
|
|
|
will belong to the user and its main group.
|
|
|
|
|
|
|
|
|
|
Examples:
|
|
|
|
|
|
|
|
|
|
----
|
|
|
|
|
foo -1 bar -1 !=blabla /home/foo /bin/sh alpha,bravo Foo user
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
This will create this user:
|
|
|
|
|
|
|
|
|
|
- +username+ (aka login name) is: +foo+
|
|
|
|
|
- +uid+ is computed by Buildroot
|
|
|
|
|
- main +group+ is: +bar+
|
|
|
|
|
- main group +gid+ is computed by Buildroot
|
|
|
|
|
- clear-text +password+ is: +blabla+, will be crypt(3)-encoded, and login is disabled.
|
|
|
|
|
- +home+ is: +/home/foo+
|
|
|
|
|
- +shell+ is: +/bin/sh+
|
|
|
|
|
- +foo+ is also a member of +groups+: +alpha+ and +bravo+
|
|
|
|
|
- +comment+ is: +Foo user+
|
|
|
|
|
|
|
|
|
|
----
|
|
|
|
|
test 8000 wheel -1 = - /bin/sh - Test user
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
This will create this user:
|
|
|
|
|
|
|
|
|
|
- +username+ (aka login name) is: +test+
|
|
|
|
|
- +uid+ is : +8000+
|
|
|
|
|
- main +group+ is: +wheel+
|
|
|
|
|
- main group +gid+ is computed by Buildroot, and will use the value defined in the rootfs skeleton
|
|
|
|
|
- +password+ is empty (aka no password).
|
|
|
|
|
- +home+ is +/+ but will not belong to +test+
|
|
|
|
|
- +shell+ is: +/bin/sh+
|
|
|
|
|
- +test+ is not a member of any additional +groups+
|
|
|
|
|
- +comment+ is: +Test user+
|
