how embarassing ! This turns out to be a bug in infptrace.c. Below
is a patch. Could some kind soul apply it ?

where one or more of the non-default domains are not yet bound.
If we make a YP request for a domain other than the default domain,
and there is no binding for the new domain yet, _yp_dobind() sees
that the /var/yp/binding/DOMAIN.VERS file for the unbound domain is
not locked (by ypbind) and from this it concludes that the NIS system
is dead, so it gives up.
This behavior has been changed: before giving up in this case, we now
make a second check to see if the binding file for the *default* domain
is also not locked. Only if the default domain binding file is also
unlocked to we now assume that ypbind has bought the farm and bail out.
(Note: this assumes that the user hasn't changed the default domain
while ypbind is running.)
With this change, _do_ypbind() is allowed to proceed into the next
section of code wherein it prods ypbind into establishing a binding
for the new domain. This first call times out after ten seconds,
after which it should retry and succeed. From then on, the binding
for the second domain should be handled normally.
new driver code, there are diffs to several other existing files
on the system and a man page.
This version of matcd implements the rest of the key ioctls related to
playing audio CDs and reading table of contents information from any
type of disc.
This update also corrects several problems detected since the original
version 1(10) was released. These include:
1. Jordons report on the kernel -c string problem.
2. A problem with the driver being confused by other types of
devices located at addresses it probes.
3. An old CD TOC wouldn't always be cleared after a disc change.
4. Cleaned up code so -Wall yields no warnings on 2.0 and later.
5. A problem with drive getting out of sync with the driver when
changing between CD-Data and CD-DA.
There have only been two reports from the field relating to problems
so either the first release isn't really being used or doesn't have
many problems.
If there are any problems with this submission, please let me know.

1. pkg_create now has a -P argument for specifying dependencies on the
command line.
2. pkg_add will honor dependencies and chain-load them automatically if
it finds the required package(s) in the same directory as the package
that is being loaded. For best results, install packages from a directory
containing all the packages you'll possibly need
(like /usr/ports/packages/all).
2 remaining flaws:
1. pkg_add looks in one place (where you were when you loaded the primary
pkg) for depended packages. If you can come up with a search path scheme
that's not a total hack - be my guest!
2. Recursive dependency expansion can result in the name of a dep being
listed more than once. This doesn't bother pkg_add since it checks
for package existance with pkg_info and will skip already-loaded packages.
I don't know how/if pkg_delete handles this yet, however. I need to look
into it.
all .tgz files go to /usr/ports/packages/.packages, and a relative
symlink is created for every item in CATEGORIES...i.e., if "CATEGORIES
= foo bar", then /usr/ports/packages/{foo,bar}/pkgname.tgz both point
to /usr/ports/packages/.packages/pkgname.tgz.

bits) along, and rmt did the wrong thing in calling open(2) with random
garbage as third parameter. Make it create new files with 0666
(modified by the umask of the remote shell anyway).
This removed the last show-stopper from tar not working with remote
archives.
Also please note that previous commit regarding UH24F controller was
misattributed to Poul - it was Steve's!

Three people have reported that this fixes the problem they are having.
Submitted by: Steve Gerakines <steve2@genesis.tiac.net>
Fixed remaining known bugs in the buffer IO and VM system.
vfs_bio.c:
Fixed some race conditions and locking bugs. Improved performance
by removing some (now) unnecessary code and fixing some broken
logic.
Fixed process accounting of # of FS outputs.
Properly handle NFS interrupts (B_EINTR).
(various)
Replaced calls to clrbuf() with calls to an optimized routine
called vfs_bio_clrbuf().
(various FS sync)
Sync out modified vnode_pager backed pages.
ffs_vnops.c:
Do two passes: Sync out file data first, then indirect blocks.
vm_fault.c:
Fixed deadly embrace caused by acquiring locks in the wrong order.
vnode_pager.c:
Changed to use buffer I/O system for writing out modified pages. This
should fix the problem with the modification date previous not getting
updated. Also dramatically simplifies the code. Note that this is
going to change in the future and be implemented via VOP_PUTPAGES().
vm_object.c:
Fixed a pile of bugs related to cleaning (vnode) objects. The performance
of vm_object_page_clean() is terrible when dealing with huge objects,
but this will change when we implement a binary tree to keep the object
pages sorted.
vm_pageout.c:
Fixed broken clustering of pageouts. Fixed race conditions and other
lockup style bugs in the scanning of pages. Improved performance.

drivers to protect DDB from being invoked while the console is in
process-controlled (i.e., graphics) mode.
Implement the logic to use this hook from within pcvt. (I'm sure
Søren will do the syscons part RSN).
I've still got one occasion where the system stalled, but my attempts
to trigger the situation artificially resulted int the expected
behaviour. It's hard to track bugs without the console and DDB
available. :-/
