I think in the default configuration sysklogd will rotate the mentioned logfiles itself, not logrotate. This is because logrotate is no longer part of the default installation.
The sysklogd package comes with the cron jobs /etc/cron.daily/sysklogd and /etc/cron.weekly/sysklogd. These rotate syslog daily and /var/log/mail.warn /var/log/uucp.log /var/log/user.log /var/log/daemon.log /var/log/messages /var/log/debug /var/log/auth.log /var/log/mail.err /var/log/mail.log /var/log/kern.log /var/log/lpr.log /var/log/mail.info weekly. Thus logrotate doesn't need to rotate them too. -- default config doesn't rotate syslog & al https://launchpad.net/bugs/51879 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
