"type" is a built-in in POSIX shells, and even the pre-historic SunOS
/bin/sh has a "type" built-in, be it a bare-bones version that does not
support the "-p" switch, that is sufficient. So another possibility is:

    set -- `type find`
    shift `expr $# - 1`
    # Now, $1 is the full path of "find".
    # ...

This said, the `postconf -h queue_directory` solution is likely simplest
for now.
