The second release of 2.10BSD is now available. It has been desig-
nated 2.10.1BSD. Although the changes between it and the first release
of 2.10BSD are fairly simple to describe, they cover large portions of
the distribution. Most will not be visible to either users or adminis-
trators; specifically, no recompilation is necessary. Administrators
should be aware that the 4.3BSD disk quota system is now available.
Due to address space considerations, however, it is expensive to run.
Also, the source for the on-line manual pages has been rearranged as
per the 4.3BSD-tahoe release.
The major change, and the reason for the second release, is an exten-
sive reworking of the kernel to move the networking into supervisor space.
This move eliminated most, if not all, of the instabilities seen in the
original networking provided with 2.10BSD; it also doubled the speed of,
for example, file transfer. As encouragement to sites that encountered
difficulties in using the networking in the first release, beta sites have
been running for months without crashing, as well as sites with over fifty
nodes. 2.10.1BSD supports DEQNA's, DEUNA's, DELUA's, Interlan's and 3Com
ethernet boards, as well as SLIP. Drivers for various other networking
devices are provided, but are untested, and, in many cases, unported.
In application land, many missing pieces of the 4BSD distribution
have been added, most notably the FORTRAN compiler and library and the
line printer sub-system. Many other programs have had minor (and not-so-
minor) fixes applied.
Finally, credit where it's due: Cyrus Rahman, of Duke University, is
responsible for much of the work done to fix various applications for
2.10.1BSD. Steven Schultz, of Contel Federal Systems, did the original
port of the supervisor space networking, as well as much of the debugging.
This release would not have been possible without their efforts.
Because the changes to the kernel are major, no ``upgrade'' tape will
be available. 2.10.1BSD is only available as a source release, to
appropriate licensees of V7, System III, System V, or 2.9BSD. The cost is
$200, prepaid. Note, 2.10.1BSD requires split I&D, and at least 1/2Mb of
memory.
The release consists of two 2400 foot, 1600 bpi tapes (approximately
80Mb) and approximately 100 pages of documentation. If you require 800
bpi tapes, please contact USENIX for more information.
Also, there are a few copies of 2.9BSD available. If you do not have
split I&D and want UNIX for your PDP-11, contact the USENIX office.
