Hi Ben,
I attached a perl script to this email that will let you turn an rpm
into a cpio file. To use it do:

rpm2cpio some.file.rpm | cpio --extract

Hope this helps.

Jim
#! /usr/bin/env perl

# why does the world need another rpm2cpio? because the existing one
# won't build unless you have half a ton of things that aren't really
# required for it, since it uses the same library used to extract RPM's.
# in particular, it won't build on the HPsUX box i'm on.

# add a path if desired
$gzip = "gzip";

sub printhelp {
print "rpm2cpio, perl version by orabidoo <odar\@pobox.com>\n";
print "use: rpm2cpio [file.rpm]\n";
print "dumps the contents to stdout as a GNU cpio archive\n";
exit 0;
}

if ($#ARGV == -1) {
printhelp if -t STDIN;
$f = "STDIN";
} elsif ($#ARGV == 0) {
open(F, "< $ARGV[0]") or die "Can't read file $ARGV[0]\n";
$f = 'F';
} else {
printhelp;
}

printhelp if -t STDOUT;

# gobble the file up
undef $/;
$|=1;
$rpm = <$f>;
close ($f);

($magic, $major, $minor, $crap) = unpack("NCC C90", $rpm);

die "Not an RPM\n" if $magic != 0xedabeedb;
die "Not a version 3 RPM\n" if $major != 3;

$rpm = substr($rpm, 96);

while ($rpm ne '') {
$rpm =~ s/^\c@*//s;
($magic, $crap, $sections, $bytes) = unpack("N4", $rpm);
$smagic = unpack("n", $rpm);
last if $smagic eq 0x1f8b;
die "Error: header not recognized\n" if $magic != 0x8eade801;
$rpm = substr($rpm, 16*(1+$sections) + $bytes);
}

die "bogus RPM\n" if $rpm eq '';

open(ZCAT, "|gzip -cd") || die "can't pipe to gzip\n";
print STDERR "CPIO archive found!\n";

print ZCAT $rpm;
close ZCAT;
