The hotplug rules live in a single /etc/hotplug.json, so a package that needs a device node named, owned or grouped its own way has no way to contribute one; the alternatives are patching the shared file or falling back to a shell script under /etc/hotplug.d. Load /etc/hotplug.json.d/*.json from inside the device node branch, ahead of the built-in name rules, and /etc/hotplug-preinit.json.d/* at the end of the preinit script. Fragments are run in sorted order. A fragment that creates a node keeps it: the generic rule below still runs, but its mknod() fails with EEXIST and leaves the node alone. This is done in preparation for deprecating some of the subtarget-wide FEATURES flags, instead introducing feature-umbrella packages such as `video-support` and `audio-support` shipping the hotplug rule snippets and having all providers (ie. kmods) and users depend on them.
