Actually, it is more natural to standardized around a unified interface ala snmp . /dev/hairydevicename with its godzilla ioctl and matching hairy control program is not intuitive nor a centralized mechanism to access both the kernel and its devices. sysctl type interface could easily be extended to support multiple variables: sysctl -w hw.bt848.1.mute=1 hw.bt848.2.tuner=0. If I want to find out all the bt848 devices on the system: sysctl hw.bt848 which does a snmplike walk on the node hw.bt848 Incidentely, you can still maintain the device control programs as shell wrappers which just use sysctl commands;however, the converse is not true.
