res_init.c 1.20 broke non-INET6 kernel!
All nameservers are initialized to AF_INET6 which cause socket() to return -1 in non-INET6 kernel. All names lookups fails as result. I think IPV6 support is optional, isn't?

HEADSUP: bioops patch.
This patch virtualizes untangles the bioops operations vector.
Background:
The bioops operation vector is a list of OO-like operations which can
be performed on struct buf. They are used by the softupdates code
to handle dependencies.
Ideally struct buf should have had a real OO like operations vector
like vnodes have it, and struct bioops is the first step towards that.
One of the reasons we should have OO-like struct buf, is that as
long as bwrite(bp) "knows" that the buffer is backed by a disk
device, we cannot use the UFS layer on top of a storage manager
which isn't based on disk-devices: When UFS modifies a directory
inode, it will call bwrite(bp) on the buffer with the data. This
would not work if the backing were based on malloc(9) or anonymous
swap-backed VM objects for instance.
In other words: this is the main reason why we don't have a decent
tmpfs in FreeBSD.
Instead of just assuming that it works on a disk, bwrite(bp) should
do a "bp-b_ops-bwrite(bp)" so that each buffer could have its own
private idea of how to write itself, depending on what backing it has.
So in order to move bioops closer to become a bp-b_ops, this patch
takes two entries out of bioops: the "sync" and the "fsync" items
and virtualizes the rest of the elements a bit.
The "sync" item is called only from the syncer, and is a call to the
softupdates code to do what it needs to do for periodic syncing.
The real way of doing that would be to have an event-handler for this
since other code could need to be part of the sync trafic, raid5
private parity caches could be one example. I have not done this
yet, since currently softupdates is the only client.
The fsync item really doesn't belong in the fsync system call, it
belongs in ffs_fsync, and has been moved there.
To give the right behaviour when SOFTUPDATES is not compiled in,
stubs for both of these functions have been added to ffs_softdep_stub.c
Finally all the checks to see if the bioops vector is populated
has been centralized in in-line functions in sys/buf.h thereby
paving the road for the global bioops to become bp-b_ops.
Comments, reviews, tests please

Re: HEADS UP!: config changes...
Hello Peter! I just have things running. I see that the kernel boots _much_ faster now. I don't know, if you wanted that or if this is a nice side-effect. However, a few comments, which might be of interest. Some of those are probably planned by you already. a) the device.hints file: It will probably be copied to /sys/compile by config(8) in future and installed by make install :) Good. b) Setting apm 0 at to nexus (string) Setting apm 0 disabled to 1 (int) Setting apm 0 flags to 32 (int) ... Can this be moved to verbose boot only? c) is much more interesting: With the new kernel my syscons scrolling stopped working. However, this could also be jake's fault, I'll ask him.
