make_dev() call.
At the moment, it is an error for anyone but root to write to this
device (EPERM), and the permissions don't suggest that. Soon, however,
anyone will be able to write here, but only root will cause an implicit
reseed.
X field is treated the same as the unit number for acdX. The optional
Y parameter specifies the number of track devices to create starting at
track 1. If Y is not specified, it defaults to 100.
- Add the acd0t target to the all target to preserve previous behavior.
- Don't add the acd0t target to the fixit target, thus keeping the fixit
floppy from running out of i-nodes.
The tap driver is used to present a virtual Ethernet interface to the
system. Packets presented by the network stack to the interface are
made available to a character device in /dev. With tap and the bridge
code, you can make remote bridge configurations where both sides of
the bridge are separated by userland daemons.
This driver also has a special naming hack to allow it to serve a similar
purpose to the vmware port.

Supported devices:
SB Midi Port (sbc + midi)
SB OPL3 (sbc + midi)
16550 UART (midi, needs a trick in your hint)
CS461x Midi Port (csa + midi)
OSS-compatible sequencer (seq)
Supported playing software:
playmidi (We definitely need more)
Notes:
/dev/midistat now reports installed midi drivers. /dev/sndstat reports
only pcm drivers. We need the new name(pcmstat?).
EMU8000(SB AWE) does not sound yet but does get probed so that the OPL3
synth on an AWE card works.

2. Newbusify the driver.
3. Build as a module.
4. Use correct minor numbers when creating device files.
5. Correctly lock control characters.
6. Return ENXIO when device not configured.

Note:
- the old driver still lives in src/sys/i386/isa, so that you can
revert to it if something goes wrong.
- The module does not detach very well. Attaching works fine.
/dev/xxx and one /dev/rxxx. This changes them to a hard link so that
less inodes are consumed and so that the permissions are always in sync.
There are lots more of these still.
symlinks to fd/0, fd/1, and fd/2 respectively. This will make
things easier for upcoming changes to fdesc (and does not break
anything for the current state of things) and hopefully its
position as the replacement for our existing static /dev/fd nodes.

MAKEDEV all, making DHCP on multiple interfaces happier, and allowing use
of tcpdump to to debug DHCP, without creating more devices.
(we need devfs)
Modify MAKEDEV to create four tun devices in MAKEDEV all as well, since
we're being gratuitous with network pseudo-devices.

strictly a security hole, but neither is it a very good idea. Replace
it with a symlink to /dev/null to happify programs that expect it.
It is suggested that users of the jail environment modify the jail's
syslog.conf to not send stuff to /dev/console, but instead syslog
it somewhere else. Such as a loghost, potentially even to the host
environment's syslog.

devices because accessible by group wheel instead of group operator.
Didn't fix fishy group for rsa*.ctl. This device should have group operator
if that is safe, or mode 600 and group wheel.
Removed ssc and uk*.
Removed bogus (redundant) chmod's to 600.

Also, remove all but the ums0 device from the fixit target 'to save
precious i-nodes on the fixit floppy'.
We were supposed to get these in far earlier and didn't, hence
the commit after feature freeze. A promise is a promise. :)

Improve the internal mknod() to understand being passed an (optional)
user:group specification.
Don't apply root:wheel to nodes explicitly anywhere, it's the default.
Remove an odd looking uucp:wheel assignment, as it's inconsistent with
all the other tty?? devices.

Fixed some style bugs for cam (superflous umask and missing newline).
Fixed bogons for apm. The pattern "apm*" matched too many things; apm
and apmctl were both made twice by `MAKEDEV all'. Hopefully no one
depends on `MAKEDEV apm0' making apm or on `MAKEDEV apm' making apmctl.
MAKEDEV can now run (with /sbin/chown and /bin/chgrp, still) without
any /usr. The default PATH for MAKEDEV is now "/sbin:/bin" to prevent
against further spammage of /usr programs in MAKEDEV. In the event
of an emergency, the variable "MAKEDEVPATH" can be used to replace
PATH, but I don't know what that emergency could be.
Let me know if you have any problems. I've tested it as well as
I could, which basically means everything except for RocketPorts.

longer really suitable as a default to create the various /dev nodes
to be contained on the fixit floppy, since all our proud new devide
nodes finally made the fixit floppy run over...
So instead create a new target titled `fixit' which creates just the
dev nodes for a single unit per each default driver; whoever needs
more of them is free to create whatever he needs, perhaps after
killing unused nodes before. There were more than 700 /dev nodes on
the floppy before that action, and it's still around 350 now. I doubt
all the various /dev/ugen* entries are really useful on such a tool,
so people, please check, and if you feel like more could be eliminated
from that floppy, kill'em.
While i was at it, removed traces of ft(8) that still survived even
though the driver has long since been dead.
That's step #1. #2 will follow...
