Bug#394736: the NUM_CONSOLES variable is not always set but used as if it was

[Géraud Meyer]

severity 394736 normal
thanks

In /etc/init.d/console-screen.sh in the function setup NUM_CONSOLES is
defined only if SCREEN_FONT already is set:

    # Global default font+sfm
    if [ "${SCREEN_FONT}" ]
    then
    [ "$VERBOSE" != "no" ] && log_action_begin_msg "Setting up general
console font"
    SCREEN_FONT="-f ${SCREEN_FONT}"

    # maybe use an external SFM
    [ "${SCREEN_FONT_MAP}" ] && SCREEN_FONT_MAP="-u ${SCREEN_FONT_MAP}"

    # Try to be cleverer and run for all consoles, but this is run
    # _before_ getty and so only one console running. So,
    # Set for the first 6 VCs (as they are allocated in /etc/inittab)
    NUM_CONSOLES=`fgconsole --next-available`
    NUM_CONSOLES=$(($NUM_CONSOLES - 1))
...
    fi

and then NUM_CONSOLES is used outside this if:

    # Set LEDS here
    if [ "$LEDS" != "" ]
        then
        i=1
>       while [ $i -lt $NUM_CONSOLES ]
          do
          setleds -D $LEDS < $DEVICE_PREFIX$i
          i=$(($i + 1))
        done
    fi

The config file /etc/console-tools/config does not define it and it is
the original one so I try to change the severity. I hope that's how it
is supposed to be done.

Regards
