It is time to clean up the confusing log rotating set-up on our Ubuntu servers.
Currently log rotating is done through syslog and logrotate. We will kill the syslog stuff, and use logrotate for rotating all logs.
Sysklogd will be just another process that needs to have its logs rotated by logrotate.

  1. Generate logrotate config file for sysklogd. You can ask sysklogd what files it is currently logging to, and use that as input for the logrotate config file.
    This ugly one liner will do the trick: 
    echo -e "`printf \\"\"%s\\" \" \`syslogd-listfiles -a\`` {\n\tpostrotate\n\tsharedscripts\n\t\t/etc/init.d/sysklogd reload > /dev/null\n\tendscript\n}\n" > /etc/logrotate.d/sysklogd
    Change according to your needs - defaults are in /etc/logrotate.conf - see man logrotate. Very useful option is dateext.
  2. Remove old sysklogd cron entries: 
    rm /etc/cron.*/sysklogd

This should to the trick. Started testing on Cajones on 2010-01-11.
