Updating Information for FreeBSD current users

directly to him.  See end of file for further details.

19990831:
        tn3270 has been removed from the based system and added as a port.

19990830:
        User-visible TCP timers are now expressed in units of 1ms, instead
        of 500ms, so if you've customized any timer values under
        ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.

19990828:
        RCS Id tags changed to FreeBSD.  This will cause huge cvsup
        updates.

19990821:
        On 28-May-1999 libreadline was upgraded from readline-2.2 to
        readline-4.0.  At that time the shared library major version
        number was bumped from "3" to "4".  It has been deemed that
        the interface change between readline-2.2 and readline-4.0 was
        not suffient to warrant the version number bump.

        Thus I have reverted it back to "3".  You will need to perform
        the below immediately before your next ``make world'':
            cd /usr/lib
            ls -l libreadline.so.4
                (if you have /usr/lib/libreadline.so.4)
            mv libreadline.so.4 libreadline.so.3
            rm -f libreadline.so
            ln -s libreadline.so.3 libreadline.so

19990801:
        Changes to the pccardd kernel interface require that you recompile
        pccardd for new kernel.

19980725:
        The ipfw interface to the kernel has changed.  You will need to
        recompile ipfw programs for the new kernel.

19990715:
        The bpfilter device has been renamed to bpf.  You will need to 
        change your config files in order to enable this in newer kernels.

19990704:
        src/contrib/sys/softupdates is moving to
        src/sys/contrib/softupdates.  Update your symbolic links/etc.

19990702:
        Major changes have been made to vinum and its interface.  See
        the man page (vinum(8)) for details.  Look at the concat,
        mirror and stripe commands, as well as the SIMPLIFIED
        CONFIGURATION section.

19990628:
        Newsyslog.conf has had a minor, but potentially dangerous,
        change to its username/group syntax.  The old syntax was
        user.group, while the new syntax is user:group.

19990627:
        Inetd wrapping default has changed.  Please see the updated
        man page for details.

19990623:
        Compaq Smart Raid driver committed as ida.

19990622:
        The second phase of syscons cleanup has happened.  Some
        functionality has been made optional.  For details, see
        http://www.freebsd.org/~yokota/sc_update-June.txt
        Everyone will need to re-config(8) their kernels, but old
        binaries will work with the new kernel.

19990620:
        IPFW uid/gid-based filtering support has been committed. This
        breaks binary compatibility with previous copies of
        ipfw(8). Any utilities using the ioctl()s of ipfw (especially
        ipfw(8)) need to be recompiled with the newest headers
        installed.

19990618:
        Inetd now wraps all stream-based services, including internals.
        Syslog "severity" options are honoured. Installed syslog.conf
        and hosts.allow should be checked.

19990509:
        Most of the problems with newbus have been corrected, but
        it is still current and evolving.

        libcam's ABI has changed.  You must recompile the world and
        any ports that use it.

19990427:
        Massive changes to SMP went into the tree that should speed
        things up.  However, if you experience problems with SMP 
        machines, you can back off to the PRE_SMP_VMSHARE tag in the
        CVS repository (or run an MP kernel).

19990420:
        Pccardd and the pccard bus in general seem to be broken or
        most people.  Soren has patches to make it better for some,
        but not all people.  Work is underway to make it better for
        all people.

19990416:
        new bus changes integrated into -current.  Many problems were
        initially reported, but most have been fixed.  You'll need a
        new config and to tweak your kernel config file the way that
        GENERIC was tweaked.  Keep a copy of your old kernel when
        upgrading in case your new kernel doesn't work (and report the
        breakage to current@freebsd.org).

        As of 19990421 the remaining problems/quirks are

        o sio no longer supports pnp nor pccard.  This will be corrected,
          but the new pccard code needs to be completed.
        o Some of the sound drivers broke for some people.  It seems
          inconsistant as to who/what/when/where things broke.
        o Duplicate device entries in your config do not work.  Previously
          they were silently ignored.  psm0 seems to be the most common
          duplicate choice, although some reports have come in from people
          that wired their scsi disk entries.
        o You must move the keyboard and mouse attachments from the
          isa bus to the atkbdc bus.  See GENERIC for details.
        o Machines with multiple host-pci bridges (Intel 450NX) will not
          probe the second pci bus.
        o Some probe ordering may have changed, so device naming may change
          with the new kernel.  If you have multiple devices, please double
          check to make sure they didn't move.  This is especially true
          for cards on different buses.
        o The bus attachment for vga0 is always isa0 and never pci0 when
          it is in fact a pci card.  It is safe to ignore this.
        o The format of the boot messages has changed (and is not
          guaranteed to be constant for a while) so you may see this
          in some shell scripts that diff dmesg from day to day as well
          as scripts that parse dmesg output.

19990414:
        cc -aout sometimes has problems compiling with -g, remove -g
        from those compilation units affected until this is corrected.

        cc -aout has problems with producing some threaded libraries,
        so make world -DWANT_AOUT is not functional at this time.

        Since make world for a.out isn't functional, you cannot do
        make aout-to-elf from a pre-egcs a.out system.  To work around
        this problem, make aout-to-elf using 3.1-stable first (or a
        pre egcs -current) and then a simple make world will take you
        the rest of the way with a -current source base.

19990413:
        Make -j works again for make world.  As always, use it with
        care, and be sure to try a make world w/o -j before reporting
        problems (that is, know if the problem exists w/o -j before
        reporting the problem with -j).

19990413:
        Note cc -aout, which had been broken since the conversion to
        egcs, now supposedly works.  If you have rebuilt things like
        XFree86 a.out libraries, you should rebuild them again or
        progams that use them, including netscape, will fail to work.

19990409:
        NOTE: New c++ compiler cannot be used with c++ binaries from
        the old compiler and vice versa.

19990408:
        In recent days egcs has been imported into the tree.  A number
        of problems have been discussed in -current.  Here is a highlight
        of a few of the more common ones.  With the exception of make
        -j n, they have been claimed to have been fixed.

        c++ is broken after make world: This is correct.  Because we
        changed compilers two make worlds are necessary to get C++
        working again.  The code generated by the old compiler and new
        compiler are not compatible, so things wind up being
        undefined.

        cpp is broken in make world:  There was a window where cpp
        would be built incorrectly.  The fix for this is
                cd src/gnu/usr.bin/cc
                make clean
                make all
                make install
        and this should correct your problems.  See the -current
        archives for a version of this that does moer cleaning.

        Make -j n doesn't work.  Work contiunes to make this work,
        I've seen no reports of success as of April 7th.

19990329:
        Previously, one would define "NOAOUT" to keep from building
        the legacy a.out bits.  Now one would define "WANT_AOUT" to
        build them.

19990316:
        The name of the old wd.c and atapi.c based CDROM driver has
        been changed back to wcd. So update your config file to use
        "device wcd" instead of "device acd".

19990314:
        For those of you using the VN device as a loadable module,
        please be aware that the new VN device has been committed to
        -4.x and cannot yet be used as a loadable module.  This will
        be fixed in the future.
        
19990309:
        New loader.rc mechanism.  Please see src/sys/boot/README for
        details.

19990225:
        struct proc size changed.  Recompile kernel and the
        usual suspects.  Make world if in doubt.

19990214:
        The nlpt driver has changed names back to be the lpt driver.
        See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
        for proper configuration details.

19990210:
        The 'lpt' driver is now obsolete.  Replace it with the 'nlpt'
        driver and 'ppbus' controller combination.

19990209:
        New devstat API requires recompilation of libdevstat, systat,
        iostat, vmstat and rpc.rstatd.  A new kernel is also required.
        make world + building a kernel should do all of this.  Any
        ports that use devstat need to be recompiled as well.

19990125:
        Linux threads options has gone away (they are now standard in
        the FreeBSD kernel).  A recompile of all libkvm using programs
        is in order (or better yet a make world).

19990122:
        On or about this date there was a small window when the boot
        blocks had some minor problems which seemed to force one to
        edit /etc/fstab.  This has been corrected, if you are seeing this
        problem, please rebuild and reinstall your boot blocks.

19990121:
        Vinum has changed.  The "vinum read" command has changed.  For
        updates, please see

http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current

        for details.  

        Matt Dillon committed a boatload of VM changes, for
        information please see

http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
        or
http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current

        for details.  These changes will likely not impact anybody,
        but large chagnes to the VM need at least a heads up.

19990120:
        Stable branch created.  You might want to consider using this
        branch.  It is tagged with RELENG_3.

19990119:
        More work on the syscons driver has been committed.  Since
        files moved around, you will need to reconfigure your kernel,
        and make clean; make depend before rebuilding the kernel.  No
        config file changes are needed.

19990111:
        New keyboard and video card drivers are introduced as the first
        stage of console driver reorganization.  You are required to
        update the kernel configuration file and rebuild the kernel.
        kbdcontrol, vidcontrol, and screen savers also need recompilation.
        The instruction can be found in

                http://www.freebsd.org/~yokota/sc_update.txt

        It has notes on splash screen too.

19990106:
        Robert Nordier was kind enough to make this page to enable people to
        install the new bootblocks:

                http://www.freebsd.org/~rnordier/boot.txt

        When updating to ELF, make sure that you have updated your
        /etc/rc files which have different ldconfig invocations for
        elf and aout.  Otherwise things like X will stop working with
        messages about being unable to find library files.  The
        mergemaster utility in ports/sysutils/mergemaster helps to
        keep critical files like this in sync, and its use is
        recommended.

19990104:
        Information about ELF day (see 19981230) can be found in

                http://www.freebsd.org/~peter/elfday.html

        about the upcoming change, its motivations and instructions
        for doing the upgrade.

19981230:
        You should install new bootblocks now.  The ELF kernel will
        become default soon.  In addition, you'll need to upgrade
        your userland programs to ELF before then as well.  Use
        make aout-to-elf to upgrade your userland programs (old
        a.out programs in, for example, /usr/local/bin will
        continue to work, even after the upgrade).  See src/Makefile
        for more details.

19981224:
        The old wcd driver has been deleted from the kernel.  The
        driver that replaces it is named acd.  You'll need to change
        this in your configuration files.

        Failure to do this will result in "ATAPI CD-ROMs not
        configured" at boot time.

        The floppy tape driver (ft) has been removed from the kernel,
        with no replacement driver.

19981202:
        New groups from 19981201 commented out of mtree, so they
        aren't strictly needed, but still a good idea to have.

19981201:
        New user/group added: bind.  From src/etc/master.passwd and
        src/etc/group:
                % grep <newstuff> /usr/src/etc/group 
                bind:*:53:
                % grep <newstuff> /usr/src/etc/master.passwd 
                tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
                kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
                bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin

19981118:
        PAM integrated into the tree.   Requires new /etc/pam.conf file
        to silence warnings from authentication programs (login, etc).
        See src/etc/pam.conf for a sample.

This file contains a list, in reverse chronologocal order, of major
breakages in tracking -current.  Not all things will be listed here,
and it only starts on Novemeber 18, 1998.  If you have an earlier
version of FreeBSD, you are on your own to get to November 18, 1998.

Please filter your entries through Warner (imp@village.org) so that
