become ippp (ISDN ppp) and irip (ISDN raw IP). The character device now
are called: /dev/isdn (isdnd <-> kernel communication), /dev/isdnctl (dialing
and other control), /dev/isdntrc* (tracing), /dev/isdnbchan* (raw B channel
access, i.e. for user land PPP) and /dev/isdntel* (telephone devices, i.e.
for answering machines).
* use "ln -fs foo bar" instead of "rm -f bar; ln -s foo bar"
* remove unnecessary chown root or chgrp wheel directives; older code here
didn't bother doing this, so why be inconsistent
* when making directories, don't use -p and don't redirect stdout to /dev/null
* clean up whitespace
* wrap the main parser code in a function makedev(), and call makedev
instead of "sh $0". (this is a bit faster)
* don't barf when we have fdesc mounted; just skip the devices fdesc provides
(these files should really be automagically generated...)
