    What's the significance of putting "start_services &" within a subshell?

    Hi

    I'm looking at the following command in the /etc/init.d/knoppix-autoconfig boot script:

    ( start_services & ) >/dev/tty"$LOG_CONSOLE" 2>&1 # Not in job list

    It is in the context of

    # Start services (especially /etc/rc.local) in background
    addtask "bg"; addprogress "Starting background services..."
    ( start_services & ) >/dev/tty"$LOG_CONSOLE" 2>&1 # Not in job list

    The "start_services" is a function within the "knoppix-autoconfig" script.

    Could you tell me what the significance is of putting the "start_services &"
    WITHIN A SUBSHELL (the (...) brackets)?

    It's the way to get the the function "start_services" running in the background → "&".
