I've never used DEVFS myself (yet---still running 2.1.5), but I think it fixes a specific problem (which I believe is even cited in _The Unix Hater's Handbook_): You never have to run the MAKEDEV script again. (Heck, you won't even need a MAKEDEV script.) Having entries in /dev for devices which aren't in your kernel is silly. Not having entries in /dev for devices you do have is even more silly. DEVFS fixes this. Also, the /dev entries can appear and disappear automatically for LKMs. Pretty spiffy stuff. -- Sean Kelly NOAA Forecast Systems Laboratory kelly@fsl.noaa.gov Boulder Colorado USA http://www-sdd.fsl.noaa.gov/~kelly/
