I should mention that this isn't something I'm doing for a particular set of people.
I just have a lot of time on my hands these days and a friend and I wanted to write a program that documents things for an admin automatically. I do a bit of freelance sys admin work from time to time and a lot of servers are either not documented at all or badly documented. I know this sounds a little ambitious but maybe I can start with something very small and build it up over a couple years.
Yeah, you're definitely right about configure being very customizable...but I don't know how to work around this.
You said configure is usually told where to install things. What tells it where to install things? Better yet, can you tell me where I can read more about building an installable source for Linux so that I understand what exactly goes on during the 'configure', 'make' and 'make install' process?
Regarding tracking services, watching /var/run is a reliable way to determine if a service was started, right? Or does this path also depend on what starup manager I'm using?
Thanks.

HALD(8) System Manager's Manual HALD(8)
NAME
hald - HAL daemon
SYNOPSIS
hald [options]
DESCRIPTION
hald is a daemon that maintains a database of the devices connected to the system system in real-time. The daemon connects to the D-Bus
system message bus to provide an API that applications can use to discover, monitor and invoke operations on devices. For more information
about both the big picture and specific API details, refer to the HAL spec which can be found in /usr/share/doc/hal-doc/spec/hal-spec.html
depending on the distribution.
OPTIONS
The following options are supported:
--daemon=yes|no
Specify whether to run in the foreground or the background.
--verbose=yes|no
Enable verbose debug output.
--use-syslog
Enable logging of debug output to the syslog instead of stderr. Use this option only together with --verbose.
--help Print out usage.
--version
Print the version of the daemon and exit.
BUGS AND DEBUGGING
Please send bug reports to either the distribution or the HAL mailing list, see http://lists.freedesktop.org/mailman/listinfo/hal on how to
subscribe.
First, to obtain useful debug traces you will need to have debuginfo packages installed. On a Fedora system this is in the hal-debuginfo
package and can be installed via the yum update program.
Second, shut down the existing hald daemon instance; on a Fedora system this is achieved by
/etc/init.d/haldaemon stop
After having shut down the daemon, you might want to run
pkill hald
to ensure that all the helper processe of hald are killed too. To start the HAL daemon, use
/usr/sbin/hald --daemon=no --verbose=yes
If the daemon crashes, you can start it under a debugger via
gdb /usr/sbin/hald
and then typing
run --daemon=no --verbose=yes
at the (gdb) prompt. To capture a back trace, use the bt command and attach this to the bug report.
Please also attach the output of lshal(1) in the bug report if possible (it's not possible if the hald daemon crashed). If the nature of
the bug has to do with hotplugging, attach two outputs of lshal(1) - one before the device hotplug event and one after.
