I can go through my archives if you're interested in details. From a kernel programmer's point of view, maybe it could be the best idea since null pointers, though it's nice that reading/writing/enabling a null ruleset from userland doesn't make the kernel die horribly. Details like that would be good for a devfs_ruleset_API(9) (?) man page, but From the superuser's point of view, it's basically much ado about "nothing", seems to me. :) >Since this doesn't appear to be enough, perhaps you (or anyone, for that >matter) could suggest a better way to communicate this requirement? My vote would be a direct error message like "Must specify a default ruleset", or something closer to ipfw(8)'s behavior, like Mr. Nelson was saying.
