Summary:                    start-stop-daemon not working without a pidfile
Description: 
if you call
start-stop-daemon --start --exec /sbin/syslogd
syslogd will not be startet. /sbin/syslogd is a softlink to busybox. I
guess, stat("/proc/%d/exe", &sb) leads to file statistics equal to
stat(name, &exec_stat), in function pid_is_exec of start_stop_deamon.c.
start-stop-deamon is an instance of busybox binary and should start
another busybox - the same executable, but with another applet, but it
finds itself already running -> start-stop-daemon without --pidfile option
doesn't work.

Works for me:

# start-stop-daemon --start --exec /bin/syslogd -- --help
BusyBox v1.9.0.svn (2007-12-20 23:47:50 GMT) multi-call binary

Usage: syslogd [OPTION]...
...

pid_is_exec() in svn does not compare stat() data - it compares
/proc/PID/exe target with supplied --exec NAME.
