Does it have to be a separate branch? It appears to these novice eyes that if one does not add the SLICE option to the config file, the code is pretty much out. So is the DEVFS option. So, if one does not like this code, one can leave the option out of their kernel. Besides, from what I see, it works just as well as without the devfs, plus all the benefits of a functional devfs. ---------- Sincerely Yours, Simon Shapiro Shimon@Simon-Shapiro.ORG Voice: 503.799.2313
