Since you don't think that processes with no controlling terminals are daemons, what is your definition of a daemon?
This is what my notion is -
All those processes without a controlling terminal need not be necessarily daemons and can remain as ordinary process.

Ok, let me clarify it this way.

For ex:

Code:
nohup ./check_process
detach it from terminal

[ check_process : checks whether a process is running or not ]

Since there is no terminal associated with check_process, is that a daemon ?

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. SEE ALSO
