What is a headless daemon?

[becoin]

I believe I know what is a daemon in computing, but what is a headless daemon? Besides bitcoind what other examples of headless daemons that are both clients and daemons we have in mass use currently?

A daemon is a program that runs in the background usually without direct user interaction. In the windows world this is called a service.
(http://en.wikipedia.org/wiki/Daemon_%28computer_software%29)

From http://en.wikipedia.org/wiki/Headless_system:
A headless system is a computer system or device that has been configured to operate without a monitor (the missing "head"), keyboard and mouse (KVM). A headless system is typically controlled via a network connection, although some headless system devices require a connection to be made via RS232 for administration of the device.

A headless programs is one that can run on such a machine.

So joined together a headless daemon is a process running in the background not requiring any KVM resources.

Oh and before I forget, virtually all unix daemons can be run headless. So, for example your mysql server can be counted as one (I prefer postgres if I really have to make a choice for a SQL backend, but I reckon mysql is more widely known outside the geekosphere).
