Comment 1 for bug 1378327

AFAIK, logrotate templates cannot be changed on fly out of box. I could suggest the following options to do it:
1) by CM tools (e.g. puppet agent runs) which will update /etc/logrotate.d/* as appropriate
2) by life cycle management tools, including monitoring + notifications + some triggers
3) by improving pre-deployment planning for logs storage and rotation policy as well ( there is a blueprint to address it https://blueprints.launchpad.net/fuel/+spec/manage-logs-with-free-space-consideration )
