Add log_begin_msg() and log_end_msg () in init-functions because some startup scripts need them.
if there are not two functions, then error information will arise on screen.
for example,
$ /etc/init.d/avahi-daemon start
/etc/init.d/avahi-daemon: line 161: log_begin_msg: command not found
/etc/init.d/avahi-daemon: line 163: log_end_msg: command not found
