The test suite contains:

testing "cpio -p with absolute paths" \
"echo /usr/bin | cpio -dp cpio.testdir 2>&1; echo \$?;
ls cpio.testdir" \
"\
1 blocks
0
usr
" "" ""

Where the second argument is code to evaluate and the third argument the
expected output; it expects the cpio command to print "1 blocks", the
'echo $?' command to print "0", and the ls command to print "usr"
because that directory has been copied there (without its contents).

I believe this works in all cases except where (%store-directory) is /.
Should we try to prevent such a limitation?
