It apears that more and more ./configure scripts and Makefiles make use of non-POSIXly correct shell constructs, that don't work with ash. For now, just warn the user against using ash, but keep it as an option in case newer versions of the /broken/ components come fixed, and we can again use ash, as it is in some cases really faster than bash.

config PARALLEL_JOBS

help
|
|
Number of jobs make will be allowed to run concurently.
|
|
Set this higher than the number of processors you have, but not too high.
|
|
A good rule of thumb is twice the number of processors you have.
|
|
|
|
Enter 1 (or 0) to have only one job at a time.

config LOAD

int

prompt "Maximum allowed load"
|

default 0
|
|
help
|
|
Specifies that no new jobs should be started if there are others jobs
|
|
running and the load average is at least this value.
|
|
|
|
Makes sense on SMP machines only.
|
|
|
|
Enter 0 to have no limit on the load average.
|
|
|
|
Note: only the integer part of the load is allowed here (you can't enter
|
|
0.75 for example).

Use 'sh' as CONFIG_SHELL.
|
|
|
|
./configure scripts and Makefiles make intensive use of calling
|
|
sub-shells. This is usually done by calling /bin/sh. /bin/sh ought
|
|
to be an at-least-POSIX-conformant shell (that is, able to interpret
|
|
POSIX shell scripts).
|
|
|
|
On many (most?) systems, /bin/sh is a symlink to bash. On some other
|
|
systems (eg. Ubuntu, latest Debian), /bin/sh points to dash (or ash).
|
|
bash is a full-featured shell, with many extension to POSIX, but is
|
|
quite slow (see ection BUGS in the bash man page), while dash is
|
|
faster, with very few extensions to POSIX. On the other hand, some
|
|
./configure scripts, although written to use /bin/sh, may really
|
|
require to be run by bash.
|
|
|
|
The default is to use your system's /bin/sh shell. If you want to
|
|
run faster, you can select to use dash. If you have problems with
|
|
either the system shell or when using dash, then you can force to
|
|
use bash.

NOTE: It is advised that you do NOT use ash as CONFIG_SHELL, as some
|
|
components are broken. If you decide to use ash, and the build breaks,
|
|
don't come moaning and set the CONFIG_SHELL to bash, below.
