Update of /cvs/hal/hal/doc/spec
In directory gabe:/tmp/cvs-serv12741/doc/spec

Modified Files:
	hal-spec.html 
Log Message:
2006-01-20  David Zeuthen  <davidz at redhat.com>

	Great patch from Sjoerd Simons <sjoerd at luon.net>: As most people
	probably know by now, various people don't really like that hal
	running as root. We'd much rather see only a small process running
	as root and the main hal process running unpriviledged. Which is
	exactly what this patch does :)

	How does it work? Just before drops it's root privs. a small
	program is startup which will remain running as root and does the
	real execution of the addons/probes/callouts on hals
	behalf. Communication between hald and hald-runner is done via a
	p2p dbus connection. Resulting in a process tree like this:

	  hal       /usr/sbin/hald
	  root      \_ /usr/lib/hal/hald-runner
	  root          \_ /usr/lib/hal/hald-addon-acpi
	  root          \_ /usr/lib/hal/hald-addon-storage
	  root          \_ /usr/lib/hal/hald-addon-storage

	The patch consists out of two parts. First the implementation of
	hald-runner, which is about 700 lines of code. And then a part
	transforming the hald code from the current spawning code in utils
	to an interface that can talk to the runner.

	* AUTHORS: Add Sjoerd Simons <sjoerd at luon.net>. Revise my own
	email address.

	* configure.in (AC_OUTPUT): Add hald-runner

	* Makefile.am (SUBDIRS): Add hald-runner

	* hald/Makefile.am (hald_SOURCES): add hald_runner.[ch]

	* hald-runner/utils.c, hald-runner/utils.h, hald-runner/runner.c,
	hald-runner/runner.h, hald-runner/main.c, hald-runner/Makefile.am,
	hald/linux2/osspec.c, hald/linux2/classdev.c,
	hald/linux2/blockdev.c, hald/util.[ch], hald/hald_dbus.c,
	hald/hald.c, hald/hald_runner.[ch]: New and changed files with
	slight changes. See the descriptive text above and discussion at
	http://lists.freedesktop.org/archives/hal/2006-January/004327.html
	for details. 
	Changed function hald_runner_start_runner() in hald/hald_runner.c
	to print out runner path and improve error handling when runner
	is not found. Also removed dbus_server_unref (server) in 
	handle_connection() in same file.

	* hald/haldaemon.in: Remove --retain-privileges as this is no longer
	needed

	* hald/run-hald.sh, hald/debug-hald.sh, hald/valgrind-hald.sh:
	Remove --retain-privileges and use --with-runner pointing to
	../hald-runner/hald-runner
