Don Lewis 643a8daaaf If the session leader dies, s_leader is set to NULL and getsid() may
dereference a NULL pointer, causing a panic.  Instead of following
s_leader to find the session id, store it in the session structure.

Jukka found the following info:

	BTW - I just found what I have been looking for. Std 1003.1
	Part 1: SYSTEM API [C LANGUAGE] section 2.2.2.80 states quite
	explicitly...

	Session lifetime: The period between when a session is created
	and the end of lifetime of all the process groups that remain
	as members of the session.

	So, this quite clearly tells that while there is any single
	process in any process group which is a member of the session,
	the session remains as an independent entity.

README

This is the top level of the FreeBSD source directory.  This file
was last revised on: $Id: README,v 1.12 1998/06/30 08:08:05 jkh Exp $

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel and the contents of /etc.  Please see the top of the Makefile
in this directory for more information on the standard build targets
and compile-time flags.

Building a kernel with config(8) is a somewhat more involved process,
documentation for which can be found at:
   http://www.freebsd.org/handbook/kernelconfig.html
And in the config(8) man page.

The sample kernel configuration files reside in the sys/i386/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file LINT contains entries for all possible devices, not
just those commonly used, and is meant more as a general reference
than an actual kernel configuration file (a kernel built from it
wouldn't even run).
