administrator to define certain properties of new devfs nodes before they become visible to the userland. Both static (e.g., /dev/speaker) and dynamic (e.g., /dev/bpf*, some removable devices) nodes are supported. Each DEVFS mount may have a different ruleset assigned to it, permitting different policies to be implemented for things like jails. Approved by: phk
