Given that (per bug #286556), boot_mute is used to signal "put up an image over hardware init and rc startup" (although it fails to do the latter per bug #286559), users should have the option of configuring that image through some sort of loader.conf(5) hint. The change here would be to: 1. Document the option value 2. Provide the option / respect the option When under syscons(4) versus vt(4), options such as these were surfaced in the kernel via bitmap_name and splash_bmp_load
