  • bring shell configuration in one single place
  • enhance comments; make sure we always need one /bin/sh (currently not enforced; there will be no root shell selectable if none is available; the user shell will default to /bin/sh but that isn't supplied) and one /bin/ash (either busybox ash or mksh, both work fine)

Now feel free to go and add a GNU b(lo)a(t)sh package...
configuration is similar as mksh, and it can also be used
as /bin/sh (obviously) and /bin/ash.

11 help
12 Tha 'ash' shell adds about 60k in the default configuration and is
13 the most complete and most pedantically correct shell included with
14 busybox. This shell is actually a derivative of the Debian 'dash'
15 shell (by Herbert Xu), which was created by porting the 'ash' shell
16 (written by Kenneth Almquist) from NetBSD.
17 FreeWRT needs a working /bin/ash in all cases; if you do not select
18 busybox ash make sure you enable mksh to run as /bin/ash below.

143 hush is a very small shell (just 18k) and it has fairly complete
144 Bourne shell grammar. It even handles all the normal flow control
145 options such as if/then/elif/else/fi, for/in/do/done, while loops,
146 etc.
147
148 It does not handle case/esac, select, function, here documents ( <<

161 lash is the very smallest shell (adds just 10k) and it is quite
162 usable as a command prompt, but it is not suitable for any but the
163 most trivial scripting (such as an initrd that calls insmod a few
164 times) since it does not understand any Bourne shell grammar. It
165 does handle pipes, redirects, and job control though. Adding in
166 command editing makes it a very nice lightweight command prompt.

177 The minix shell (adds just 30k) is quite complete and handles things
178 like for/do/done, case/esac and all the things you expect a Bourne
179 shell to do. It is not always pedantically correct about Bourne
180 shell grammar (try running the shell testscript "tests/sh.testcases"
181 on it and compare vs bash) but for most things it works quite well.
182 It also uses only vfork, so it can be used on uClinux systems.

198 help
199 This option causes the selected busybox shell to use busybox applets
200 in preference to executables in the PATH whenever possible. For
201 example, entering the command 'ifconfig' into the shell would cause
202 busybox to use the ifconfig busybox applet. Specifying the fully
203 qualified executable name, such as '/sbin/ifconfig' will still
204 execute the /sbin/ifconfig executable on the filesystem. This option
205 is generally used when creating a statically linked version of busybox
206 for use as a rescue shell, in the event that you screw up your system.
207
208 Note that when using this option, the shell will attempt to directly
209 run '/bin/busybox'. If you do not have the busybox binary sitting in
210 that exact location with that exact name, this option will not work at
211 all.
