Bug#57284: base: /etc/init.d/arpwatch restart fails

[Jim Dennis <jimd@starshine.org>]

Package: base
Version: 20000207
Severity: normal


 Attempting to run the command:

	/etc/init.d/arpwatch restart 

 ... fails with a message like: "arpwatch already running"

 Clearly we need a delay between the stop and start invocations.
 inserting a "sleep 1" command works fine.

 This is probably true of number of other daemons.

 Re: all init.d scripts:

 I'd suggest that the standard template for all daemon starting init.d 
 scripts be modified to include a set of ARGS to pass to the daemon
 a set of arguments as shown in the following example (10th line, and
 both instances of --start):

test -f $DAEMON || exit 0

    start-stop-daemon --start --verbose --exec $DAEMON -- $ARGS

    echo "Usage: /etc/init.d/arpwatch {start|stop|restart|force-reload}"
    exit 1
    ;;

exit 0
