dbus_enable and hald_enable
Paweł Grzyb
can you explain to me what is it : dbus_enable="YES" and
hald_enable="YES" in file /etc/rc.conf? What is their function?

Pawel

Those enable the startup of the DBUS and HAL services via their
control files in /usr/local/etc/rc.d. Those services are often
needed for X, and programs related to X (KDE, Gnome, Xfce, and
many programs that have "Use DBUS for something" compile time
options set).
Sadly, those don't provide "man dbus" or "man hal" in a very
impolite manner. I'm sure you can find more documentation on
the web, but it may already be outdated.
If you ask what HAL and DBUS actually *ARE*, I'm not sure what
to answer - to me, they are both useless. :-)
Removing the entries in /etc/rc.conf may cause problems for some
of your programs, or may even make your X stop working properly.

Try "man hald".

I believe they involved with plug-and-play devices.

I believe HAL will be going away fairly soon, with its functionality
being merged into udev on Linux.

hald is an interface between devices and programs. It listens for
attachment/detachment of input devices (keyboard, mouse, etc.) and informs
listening programs of those events.
dbus is an interprocess communication system that allows programs to connect to
and exchange messages with other programs. It allows the kernel, for example,
to interact with your desktop. Rather than you interacting directly with the
kernel, dbus acts as a middle man, controlling the communications between the
two and only allowing you to perform actions which are considered "safe" or
"reasonable".
The two work together, for example, to let your desktop know when you connect a
new mouse or type on your keyboard.
