or some variation in the path, the new version assumes that $0 is
newvers.sh path, and that dirname $0/.. is the same as $S aka $SYSDIR.
It also removes knowledge of ${MACHINE} and ${MACHINE_ARCH}, which is
also good.

during the kernel build process, the other places that call the script
do not make use of that information. So restrict execution of the
svnversion-related code to the kernel build context.
src/sys and not the entire src/ tree.
An earlier solution by peter had been comitted in r183528 and backed out
in r183566 due to problems with newvers.sh also called from other places
during world build. With the extra test this survived a make universe.
SRCDIR is seeded from `pwd` which not only means src/sys/ but
also src/include/ (and possibly src/usr.sbin/amd/include/ ?).
Trying to build world resulted in
===> include (includes)
cd /usr/src/include; make buildincludes; make installincludes
creating osreldate.h from newvers.sh
cd: can't cd to /usr/src/include/sys
*** Error code 2
as there is apparently no src/include/sys.
There are multiple possible solutions ranging from seeding SRCDIR from
the environment to adding more substitution patterns.

Proper solution to be implemented and tested by: peter
newvers.sh is run pwd is actually the obj directory, so "../../.svn"
doesn't exist and the test always fails. The second is that buildkernel
is executed with a restrictive PATH, so unless you have svnversion in
/bin or /usr/bin it can't run.
Fix this by looking for svnversion in /bin, /usr/bin, and /usr/local/bin
in that order. If found, store the location and derive the value of the
source directory. Then run svnversion in the appropriate directory.
There is one possible refinement which would be to add a test for
LOCALBASE!=/usr/local if we don't find svnversion the first time, but
IMO that's not necessary at this time.
128 bytes, 256 bytes, and 32 bytes respectively. This makes it much
easier to identify when two kernels are identical apart from a version

For the record: Problem spotted by Scott Long, who mentioned
that source upgrades from 4.7 to recent 5.x and 6.0 are broken.
Detailed analysis shows that 4.7 has a broken make(1) binary.
A breakage was fixed in RELENG_4 in make/main.c,v 1.35.2.7 by

while in fact it should have been spelled as "MFC 1.67".
set an initial value. This is aimed at getting us closer to being able to
turn -Werror back on and we can adjust the settings later on. Yes, we
could turn off -Wno-inline instead, but that would hide the effect of
gcc's bogo-estimator ignoring inline (either rightly or wrongly).

akin to all the other stuff generated by newvers.sh. In userland it is

by uname(1) by the -i flag.

kernels again, now that we're using EGCS/GCC 2.9+. This "here"
file is compatible with the Bourne shell and the Korn shell (incl. pdksh
and KSH93 from AT&T, which I do have), so it doesn't make newvers.sh
unportable, but makes it easier to modify in the future/read now.

Now I can go update my porting.sgml.
NOT a 2.2 candidate, in case phk's wondering. :)
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").

Kill the JUST_TELL_ME hack, it is no longer needed.
Kill DISTNAME, I could find no reveference to it any place in the

Now I just need to rework a few bits in release/Makefile, but want

Oh, and your now all running:
TYPE="FreeBSD"
REVISION="2.2"
BRANCH="CURRENT"
and the -BUILD-yymmdd is dead and gone. The date was already in the
version[] string, no need for it to be there in 2 formats!
We now have RELEASE=CURRENT in the CVS-tree.
If this hasn't been edited, we will use "BUILT-yyyymmdd" where the time is
that of the compile, and leave it at that, we can't do any better.
If there is no serious objections, I will modify the "cvs co" script on
freefall to fiddle this file after checkout so that it becomes
CURRENT-yyyymmdd, where the time is that of the checkout.
are running under. Here's how to bootstrap (order is important):
1) Re-compile gcc (just the driver is all you need).
2) Re-compile libc.
3) Re-compile your kernel. Reboot.
4) cd /usr/src/include; make install
You can now detect the compilation environment with the following code:
#if !defined(__FreeBSD__)
#define __FreeBSD_version 199401
#elif __FreeBSD__ == 1
#define __FreeBSD_version 199405
#else
#include <osreldate.h>
#endif
You can determine the run-time environment by calling the new C library
function getosreldate(), or by examining the MIB variable kern.osreldate.
For the time being, the release date is defined as 199409, which we have
already established as our target.
