In general, merely HUPping a daemon is deprecated because you (usually)
cannot be sure that the results are quite what you intend.  Similarly,
sending SIGTERM or SIGKILL to shut down a service, ditto.  You should,
on a conventional Linux system, use the SysVInit mechanisms, instead.  

(Less-conventional *ix systems now exist that use something radically
different from the traditional SysVInit or BSD inits, e.g., initNG,
boot-scripts, runit, syscan, launchd, SMF, upstart, eINIT.)
