In daemon mode @command{ffserver} will fork in background upon
starting, without the need to specify the "&" shell operator in the
command line. In daemon mode also @command{ffserver} will continue to
log on stdout, unlike in NoDaemon mode.

I'm not sure about what you mean by "2.4 level", and about the
interaction wih the debug mode.

I also missed the discussion about why Daemon mode was removed and
then we are re-enabling it now, so I probably miss some fundamental
information.
