According to Jim Meyering on 4/16/2008 2:33 AM:
| This test would fail not only because the built-in mknod

|       tests: avoid mkdir/selinux failure when mknod is a shell built-in
|       * tests/mkdir/selinux: Skip the mknod test if it's a built-in.

Couldn't you try to defeat the shell builtin by using a subshell and exec
to force the PATH lookup?  For example, on bash:

$ printf --version | head -n1
bash: printf: --: invalid option
printf: usage: printf [-v var] format [arguments]
$ (exec printf --version) | head -n1
printf (GNU coreutils) 6.10

Doesn't this also mean that you need to patch mknod.c to print
USAGE_BUILTIN_WARNING?

- --
Don't work too hard, make some time for fun as well!
