Depends, the stuff in /etc/cron.daily/ is executed serially, so
whatever is alphabetically after your job will not be executed until
your job completes (or at least returns the foreground shell).  Is it
OK for those jobs to wait 10-15 minutes?  If so I wouldn't worry about
backgrounding.  If not, then yes, have your shell script kick it as a
bg job.
