<para>Note however that reloading a
daemon by sending a signal (as with
the example line above) is usually not
a good choice, because this is an
asynchronous operation and hence not
suitable to order reloads of multiple
services against each other. It is
strongly recommended to set
<varname>ExecReload=</varname> to a
command that no only triggers a
configuration reload of the daemon,
but also synchronously waits for it
complete.</para>
