Each devfs mountpoint has a ruleset number associated with them. That is the number shown in /etc/devfs.rules and activated in /etc/rc.conf. Since the default rulesets in /etc/defaults/devfs.rules have numbers 1 -- 4, there is no overlap with numbers >4. So in this case there is no difference. IIRC, if you were to re-use an existing ruleset number, the rulesets are effectively merged. Since the sets 1 -- 4 are pretty restrictive, don't do that! E.g. ruleset 4 is meant for use in jails, exposing only a minimum of devices. Generally; use an unique ruleset number for each ruleset. You can use the include mechanism to incorporate other rulesets if you want to.
