+ <para>
+ BusyBox combines tiny versions of many common UNIX utilities into a single
+ small executable. It provides minimalist replacements for most of the
+ utilities you usually find in fileutils, shellutils, findutils, textutils,
+ grep, gzip, tar, etc. BusyBox provides a fairly complete POSIX environment
+ for any small or embedded system. The utilities in BusyBox generally have
+ fewer options than their full-featured GNU cousins; however, the options
+ that are included provide the expected functionality and behave very much
+ like their GNU counterparts.
+ </para>
+
+ <para>
+ BusyBox has been written with size-optimization and limited resources in
+ mind. It is also extremely modular so you can easily include or exclude
+ commands (or features) at compile time. This makes it easy to customize
+ your embedded systems. To create a working system, just add a kernel, a
+ shell (such as ash), and an editor (such as elvis-tiny or ae).

+ When you create a link to BusyBox for the function you wish to use, when
+ BusyBox is called using that link it will behave as if the command itself

+ ln -s ./BusyBox ls

+ will cause BusyBox to behave as 'ls' (if the 'ls' command has been compiled

+

+ The available actions can be classified into two groups: actions

+
+ <para>
+ Run only-once actions:
+ </para>
+
+ <para>
+ 'sysinit' is the first item run on boot. init waits until all
+ sysinit actions are completed before continuing. Following the
+ completion of all sysinit actions, all 'wait' actions are run.
+ 'wait' actions, like 'sysinit' actions, cause init to wait until
+ the specified task completes. 'once' actions are asyncronous,
+ therefore, init does not wait for them to complete. 'ctrlaltdel'
+ actions are run immediately before init causes the system to reboot
+ (unmounting filesystems with a 'ctrlaltdel' action is a very good
+ idea).
+ </para>
+
+ <para>
+ Run repeatedly actions:
+ </para>
+
+ <para>
+ 'respawn' actions are run after the 'once' actions. When a process
+ started with a 'respawn' action exits, init automatically restarts
+ it. Unlike sysvinit, BusyBox init does not stop processes from
+ respawning out of control. The 'askfirst' actions acts just like
+ respawn, except that before running the specified process it
+ displays the line "Please press Enter to activate this console."
+ and then waits for the user to press enter before starting the
+ specified process.
+ </para>
+
+ <para>
+ Unrecognized actions (like initdefault) will cause init to emit an
+ error message, and then go along with its business. All actions are
+ run in the reverse order from how they appear in /etc/inittab.

+ GNU Libc uses the Name Service Switch (NSS) to configure the

-BusyBox combines tiny versions of many common UNIX utilities into a single
-small executable. It provides minimalist replacements for most of the
-utilities you usually find in fileutils, shellutils, findutils, textutils,
-grep, gzip, tar, etc. BusyBox provides a fairly complete POSIX environment
-for any small or embedded system. The utilities in BusyBox generally have
-fewer options than their full-featured GNU cousins; however, the options
-that are included provide the expected functionality and behave very much
-like their GNU counterparts.
-
-
-</para>
-
-<para>
-BusyBox has been written with size-optimization and limited resources in
-mind. It is also extremely modular so you can easily include or exclude
-commands (or features) at compile time. This makes it easy to customize
-your embedded systems. To create a working system, just add a kernel, a
-shell (such as ash), and an editor (such as elvis-tiny or ae).

- WARNING: This field has a non-traditional meaning for BusyBox init!
- The id field is used by BusyBox init to specify the controlling tty for
- the specified process to run on. The contents of this field are
- appended to "/dev/" and used as-is. There is no need for this field to
- be unique, although if it isn't you may have strange results. If this
- field is left blank, it is completely ignored. Also note that if
- BusyBox detects that a serial console is in use, then all entries
- containing non-empty id fields will _not_ be run. BusyBox init does
- nothing with utmp. We don't need no stinkin' utmp.

-Use lash just as you would use any other shell. It properly handles pipes,
-redirects, job control, can be used as the shell for scripts (#!/bin/sh),
-and has a sufficient set of builtins to do what is needed. It does not
-(yet) support Bourne Shell syntax. If you need things like
-``if-then-else'', ``while'', and such, use ash or bash. If you just need a
-very simple and extremely small shell, this will do the job.

-GNU Libc uses the Name Service Switch (NSS) to configure the behavior of
-the C library for the local environment, and to configure how it reads
-system data, such as passwords and group information. BusyBox has made it
-Policy that it will never use NSS, and will never use and libc calls that
-make use of NSS. This allows you to run an embedded system without the need
-for installing an /etc/nsswitch.conf file and without and /lib/libnss_*
-libraries installed.
-
-
-</para>
-
-<para>
-If you are using a system that is using a remote LDAP server for
-authentication via GNU libc NSS, and you want to use BusyBox, then you will
-need to adjust the BusyBox source. Chances are though, that if you have
-enough space to install of that stuff on your system, then you probably
-want the full GNU utilities.
