No, it simply check to see if anacron is installed. Because when anacron is
installed why would anyone want cron jobs to run again. That would be
duplication of effort.
Go learn a little about shell programming.
"test -e /usr/sbin/anacron || run-parts -- report /etc/cron.daily" means
check if the /usr/sbin/anacron executable is present. If not, execute the
run-parts program with /etc/cron.daily as it's input file.
