My /etc/crontab is as follows:
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
# m h dom mon dow user command
17 * * * * root cd / && run-parts --report /etc/cron.hourly
15 4 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts
--report /etc/cron.daily )
07 3 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts
--report /etc/cron.weekly )
52 1 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts
--report /etc/cron.monthly )
I DO have anacron installed.
I do not know what is relevant from syslog.
I find no mention of cron, crontab, or logrotate in /var/log/syslog
at all.
