There's no need to create a new file.  All you need do is rename the
current logfile, then SIGUSR2 Services.  If the services.log file is not
already there (which we will assume is fact after renaming it using "mv
services.log (whatever)"), it'll create a new one for you.

That's just an extra step you don't need to do.
