o Emit everything (ioconf.*, Makefile, ...) per-attribute.
+ config(9) related metadata (cfdriver, cfattach, cfdata, ...) should be
+ collected using linker. Create ELF sections like
+ .{rodata,data}.config.{cfdriver,cfattach,cfdata}. Provide reference
+ symbols (e.g. cfdriverinit[]) using linker script. Sort entries by name
+ to lookup entries by binary search in kernel.

o Generate modular(9) related information. Especially module dependency.
+ At this moment modular(9) modules hardcode dependency in *.c using the
+ MODULE() macro:
+
+ MODULE(MODULE_CLASS_DRIVER, hdaudio, "pci");
+
+ This information already exists in config(5) definitions (files.*).
+ Extend config(5) to be able to specify module's class.
+
+ Ideally these module metadata are kept somewhere in ELF headers, so that
+ loaders (e.g. boot(8)) can easily read. One idea is to abuse DYNAMIC
+ sections to record dependency, as shared library does. (Feasibility
+ unknown.)

o Rename "interface attribute" to "bus".
