Note that "simple find" will *still* have problems doing it correctly and
securely. There was a whole thread about this back in the '95-'96 timeframe
about 'find <whatever" | xargs rm' being insecure, which lead to a discussion
of using 'find <whatever> -exec rm' which was STILL insecure.

Try this:

mkdir -p "/tmp/x /etc/"
touch "/tmp/x /etc/rc.config"

The problem is you can't 'touch /A/B/C/D' if /A/B/C and/or /A/B don't exist
yet.
