Jordan K. Hubbard 0f7a617de4 Hmm. Could have sworn I committed this before. Mention the jail() stuff 
in release notes.  Be kinda neat if the jail stuff refused to allow read/write
access to raw devices too. :)

RELEASE NOTES
FreeBSD Release 4.0-SNAP
This is a 4.0-CURRENT release SNAPshot of FreeBSD, an active
development branch which is not expected to produce a release for
some time. This line of development branched from the 3.x line
on January 20, 1999; that branch will see continuing releases and
some features of 4.0 will be back-ported.
Any installation failures or crashes should be reported by using the
send-pr command (those preferring a Web-based interface can also see
http://www.freebsd.org/send-pr.html).
For information about FreeBSD and the layout of the 4.0-RELEASE
directory (especially if you're installing from floppies!), see
ABOUT.TXT. For installation instructions, see the INSTALL.TXT and
HARDWARE.TXT files.
For the latest of these 4.0-current snapshots, you should always see:
ftp://current.freebsd.org/pub/FreeBSD
If you wish to get the latest post-3.x-RELEASE technology.

1. What's new since the 3.1/4.0 branch
--------------------------------------
All changes described here are unique to the 4.0 branch unless
specifically marked as [MERGED] features.
1.1. KERNEL CHANGES
-------------------
The VM system's anonymous storage subsystem (the ``swap pager'') has
been completely revamped.
An emulator for SVR4 binaries has been added.
Support has been added for direct access to NTFS filesystems.
Driver support has been added for PCI gigabit ethernet adapters
based on the Alteon Networks Tigon 1 and Tigon 2 chipsets, including
the Alteon AceNIC, 3Com 3c985 and Netgear GA620.
Driver support has been added for IEEE 802.11 PCMCIA wireless network
adapters based on the Lucent Hermes chipset, including the Lucent
WaveLAN/IEEE 802.11 and the Cabletron RoamAbout.
1.2. SECURITY FIXES
-------------------
A new jail(2) system call and admin command (jail(8)) have been added for
additional flexibility in creating secure process execution environments.
1.3. USERLAND CHANGES
---------------------
The base C/C++ compiler has been upgraded from GCC 2.7.2 to EGCS 1.1.2.
This gives users full ISO C++ support.
The timezone database has been updated to catch all of the recent changes
in Europe, the former Soviet Union, and Central and South America.
The timezone data files now contain a magic number allowing for easy
identification.
The f77 emulation via f2c has been updated to a current version.
The Internet Software Consortium's DHCP client has been added to the
base system.
Groff/troff/eqn has been updated to version 1.11.
Gdb has been updated to version 4.18 and is now part of the standard
release for FreeBSD/alpha.
2. Supported Configurations
---------------------------
FreeBSD currently runs on a wide variety of ISA, VLB, EISA and PCI bus
based PC's, ranging from 386sx to Pentium class machines (though the
386sx is not recommended). Support for generic IDE or ESDI drive
configurations, various SCSI controller, network and serial cards is
also provided.
What follows is a list of all peripherals currently known to work with
FreeBSD. Other configurations may also work, we have simply not as yet
received confirmation of this.

3. Obtaining FreeBSD
--------------------
You may obtain FreeBSD in a variety of ways:
3.1. FTP/Mail
-------------
You can ftp FreeBSD and any or all of its optional packages from
`ftp.freebsd.org' - the official FreeBSD release site.
For other locations that mirror the FreeBSD software see the file
MIRROR.SITES. Please ftp the distribution from the site closest (in
networking terms) to you. Additional mirror sites are always welcome!
Contact freebsd-admin@FreeBSD.org for more details if you'd like to
become an official mirror site.
If you do not have access to the Internet and electronic mail is your
only recourse, then you may still fetch the files by sending mail to
`ftpmail@ftpmail.vix.com' - putting the keyword "help" in your message
to get more information on how to fetch files using this mechanism.
Please do note, however, that this will end up sending many *tens of
megabytes* through the mail and should only be employed as an absolute
LAST resort!
3.2. CDROM
----------
FreeBSD 3.0-RELEASE and 2.2.x-RELEASE CDs may be ordered on CDROM from:
Walnut Creek CDROM
4041 Pike Lane, Suite D
Concord CA 94520
1-800-786-9907, +1-925-674-0783, +1-925-674-0821 (FAX)
Or via the Internet from orders@cdrom.com or http://www.cdrom.com.
Their current catalog can be obtained via ftp from:
ftp://ftp.cdrom.com/cdrom/catalog
Cost per -RELEASE CD is $39.95 or $24.95 with a FreeBSD subscription.
FreeBSD SNAPshot CDs, when available, are $39.95 or $14.95 with a
FreeBSD-SNAP subscription (-RELEASE and -SNAP subscriptions are entirely
separate). With a subscription, you will automatically receive updates as
they are released. Your credit card will be billed when each disk is
shipped and you may cancel your subscription at any time without further
obligation.
Shipping (per order not per disc) is $5 in the US, Canada or Mexico
and $9.00 overseas. They accept Visa, Mastercard, Discover, American
Express or checks in U.S. Dollars and ship COD within the United
States. California residents please add 8.25% sales tax.
Should you be dissatisfied for any reason, the CD comes with an
unconditional return policy.
4. Upgrading from previous releases of FreeBSD
----------------------------------------------
If you're upgrading from a previous release of FreeBSD, most likely
it's 3.0 and some of the following issues may affect you, depending
of course on your chosen method of upgrading. There are two popular
ways of upgrading FreeBSD distributions:
o Using sources, via /usr/src
o Using sysinstall's (binary) upgrade option.
[insert other notes here]
5. Reporting problems, making suggestions, submitting code.
-----------------------------------------------------------
Your suggestions, bug reports and contributions of code are always
valued - please do not hesitate to report any problems you may find
(preferably with a fix attached, if you can!).
The preferred method to submit bug reports from a machine with
Internet mail connectivity is to use the send-pr command or use the CGI
script at http://www.freebsd.org/send-pr.html. Bug reports
will be dutifully filed by our faithful bugfiler program and you can
be sure that we'll do our best to respond to all reported bugs as soon
as possible. Bugs filed in this way are also visible on our WEB site
in the support section and are therefore valuable both as bug reports
and as "signposts" for other users concerning potential problems to
watch out for.
If, for some reason, you are unable to use the send-pr command to
submit a bug report, you can try to send it to:
freebsd-bugs@FreeBSD.org
Note that send-pr itself is a shell script that should be easy to move
even onto a totally different system. We much prefer if you could use
this interface, since it make it easier to keep track of the problem
reports. However, before submitting, please try to make sure whether
the problem might have already been fixed since.
Otherwise, for any questions or tech support issues, please send mail to:
freebsd-questions@FreeBSD.org
Additionally, being a volunteer effort, we are always happy to have
extra hands willing to help - there are already far more desired
enhancements than we'll ever be able to manage by ourselves! To
contact us on technical matters, or with offers of help, please send
mail to:
freebsd-hackers@FreeBSD.org
Please note that these mailing lists can experience *significant*
amounts of traffic and if you have slow or expensive mail access and
are only interested in keeping up with significant FreeBSD events, you
may find it preferable to subscribe instead to:
freebsd-announce@FreeBSD.org
All of the mailing lists can be freely joined by anyone wishing
to do so. Send mail to MajorDomo@FreeBSD.org and include the keyword
`help' on a line by itself somewhere in the body of the message. This
will give you more information on joining the various lists, accessing
archives, etc. There are a number of mailing lists targeted at
special interest groups not mentioned here, so send mail to majordomo
and ask about them!
