Interesting, It would be nice as a command line switch like '-d'
(or maybe even better another line in config?)
So the admin can decide what is more important to keep the service
always up or to be sure the logs are preserved.

If you turn on debugging on one service (e.g. openldap) it is better to remove only
it's logs and not the others (e.g. auth logs).

What do you think?
