>Description:
crunchgen is built as a host tool for building boot disks.  At line 626 of
crunchgen/crunchgen.c, though, we see:

    if((f = popen(line, "r+")) == NULL) {

According to the glibc documentation, it only supports "r" and "w".
Similarly, the popen(3) manual page on NetBSD points out that this usage
isn't portable.

>How-To-Repeat:
Try to use nbcrunchgen built on a Linux system.  Get this error message:
submake pipe: Invalid argument

>Fix:
Maybe change that to "r".  I don't think f is ever written to.
