this gives us several benefits, including:
* easier extensibility- new optional methods can be added to
ac97/mixer/channel classes without having to fixup every driver.
* forward compatibility for drivers, provided no new mandatory methods are

Apply a more consistent style to the echo statements in /etc/ scripts.
* Put quotes around each line
* Single quotes for lines with no variable interpolation
* Double quotes if there is
* Capitalize each word that begins a line
* Make echo -n 'Doing foo:' ... echo '.' more of a standard
Also:
* Use rm -f on /var/run/dev.db so if it's not there (devfs) it doesn't error
* Shorten the ldconfig messages so that the default fits on one line
* Test whether /var/msgs/bounds is a link before overwriting it
* Generally futz around with whitespace

messages send by routers when they deny our traffic, this causes
a timeout when trying to connect to TCP ports/services on a remote
host, which is blocked by routers or firewalls.
rfc1122 (Requirements for Internet Hosts) section 3.2.2.1 actually
requi re that we treat such a message for a TCP session, that we
treat it like if we had recieved a RST.
quote begin.
A Destination Unreachable message that is received MUST be
reported to the transport layer. The transport layer SHOULD
use the information appropriately; for example, see Sections
4.1.3.3, 4.2.3.9, and 4.2.4 below. A transport protocol
that has its own mechanism for notifying the sender that a
port is unreachable (e.g., TCP, which sends RST segments)
MUST nevertheless accept an ICMP Port Unreachable for the
same purpose.
quote end.
I've written a small extension that implement this, it also create
a sysctl "net.inet.tcp.icmp_admin_prohib_like_rst" to control if
this new behaviour is activated.
When it's activated (set to 1) we'll treat a ICMP administratively
prohibited message (icmp type 3 code 9, 10 and 13) for a TCP
sessions, as if we recived a TCP RST, but only if the TCP session
is in SYN_SENT state.
The reason for only reacting when in SYN_SENT state, is that this
will solve the problem, and at the same time minimize the risk of
this being abused.
I suggest that we enable this new behaviour by default, but it
would be a change of current behaviour, so if people prefer to
leave it disabled by default, at least for now, this would be ok
for me, the attached diff actually have the sysctl set to 0 by
default.

In a few days I will commit a patch which changes vn(4) to use the
disk-minilayer. This will make vn(4) fully DEVFS friendly but have
the side effect that vnconfig needs the vn%d.ctl devices to be able
to configure vn(4).
Please remake your /dev/vn entries with this revision of MAKEDEV if
you don't rung DEVFS already.
