Re: CS4232 loop

Hi,
	This is an FAQ. It is also covered in kernel-package's Problem
 list, /usr/doc/kernel-package/Problems.gz. I am including an
 excerpt. 

	Hope this helps,

  d) make-kpkg goes into an infinite loop when trying to make oldconfig.

    This is _not_ a bug with kernel-package, it is a well known
    incompatibility between the new version of expr (which has suddenly
    become POSIX compliant) and the kernel sources (which did not expect
    expr to behave this way).

    The fix is to apply the following patch to the kernel sources.

 A little retrospection shows that although many fine, useful software
 systems have been designed by committees and built as part of
 multipart projects, those software systems that have excited
 passionate fans are those that are the products of one or a few
 designing minds, great designers.  Consider Unix, APL, Pascal,
 Modula, the Smalltalk interface, even Fortran; and contrast them with
 Cobol, PL/I, Algol, MVS/370, and MS-DOS. Fred Brooks, Jr.
