Major: When blocking occurs in allocbuf() for VMIO files,
excess wire counts could accumulate.
Major: Pages are incorrectly accumulated into the physical
buffer for clustered reads. This happens when bogus
page is needed.
Minor: When reclaiming buffers, the async flag on the buffer
needs to be zero, or the reclaim is not optimal.
Minor: The age flag should be cleared, if a buffer is wanted.
- Add the .PHONY, .PARALLEL, and .WAIT directives
- Added the -B and -m commandline flags
- misc. man page cleanups
- numerous job-related enhancements
- removed unused header file (bit.h)
- add util.c for functions not found in other envs.
- and a few coordinated whitespace changes
Special thanks to Christos Zoulas <christos@netbsd.org>
for help in the merge. A 'diff -ur' between Net and
FreeBSD now only contains sccsid-related diffs. :)

-hdr and -ftr
Specify files to insert at the top and bottom of every
page. This is similar in result to the existing -ssi
option but everything happens at build time. If the
string @@UPDATED@@ appears in either file it will be
replaced with "Updated" followed by the current date.
-white
Make the pages black text on white background.
For me, more often than not, the backgrounded syslogd daemon is not
yet ready to process log messages before other things (such as named)
want to log a heap of them. It seems that it's the O_SYNC writes of
the stuff coming in from /dev/klog that's the slowdown.
Anyway, instead of using the libc daemon, roll a modified version. This
one has a timeout. The child will wait for either the timeout to expire
or the child process to signal it to let it know that it's "ready" and
the /dev/log socket is set up and active, so it's safe to continue the
boot. It adds a small fraction of a second pause to the boot time, but on
the other hand the overall boot time is *quicker* since the disk is not
being thrashed while the log messages are getting written out synchronously
one by one while other daemons are loading in parallel.
The timeout is in case the child segfaults or something before becoming
fully operational.
SLIP/PPP devices, putting them before the others in the network device
selection menu.
2. Change "Other" to "URL" so as not to conflict with the keyboard accellerator
for the "OK" button in FTP site selection menu.
3. Detect the NULL last symbol in the name list and initialize the other
members correctly.
First, change sysinstall and the Makefile rules to not build the kernel
nlist directly into sysinstall now. Instead, spit it out as an ascii
file in /stand and parse it from sysinstall later. This solves the chicken-n-
egg problem of building sysinstall into the fsimage before BOOTMFS is built
and can have its symbols extracted. Now we generate the symbol file in
release.8.
Second, add Poul-Henning's USERCONFIG_BOOT changes. These have two
effects:
1. Userconfig is always entered, rather than only after a -c
(don't scream yet, it's not as bad as it sounds).
2. Userconfig reads a message string which can optionally be
written just past the boot blocks. This string "preloads"
the userconfig input buffer and is parsed as user input.
If the first command is not "USERCONFIG", userconfig will
treat this as an implied "quit" (which is why you don't need
to scream - you never even know you went through userconfig
and back out again if you don't specifically ask for it),
otherwise it will read and execute the following commands
until a "quit" is seen or the end is reached, in which case
the normal userconfig command prompt will then be presented.
How to create your own startup sequences, using any boot.flp image
from the next snap forward (not yet, but soon):
% dd of=/dev/rfd0 seek=1 bs=512 count=1 conv=sync <<WAKKA_WAKKA_DOO
USERCONFIG
irq ed0 10
iomem ed0 0xcc000
disable ed1
quit
WAKKA_WAKKA_DOO
Third, add an intro screen to UserConfig so that users aren't just thrown
into this strange screen if userconfig is auto-launched. The default
boot.flp startup sequence is now, in fact, this:
USERCONFIG
intro
visual
(Since visual never returns, we don't need a following "quit").

1/ session leader
2/ Have a console device vnode (/dev/console)
3/ have NULL pointer for a consoel tty struct.
fix the only case where the tty struct is referenced without a prior
check for existance.
