Thanks for your reply. When I'll install the mysql database server on the box, the lot of "gentoo-like" things will require it localy. For example, when I emerge php with mysql support, the apache rc script will contains something like "use mysql ....", or "need mysql" in that depend part. When I emerge something else with mysql support too, it will containts this thing too. And when I try to restart some of that, or when I wanna to restart the box, the mysql server will be started and it will take more time, as is realy needed. I wouldn't like that... I can edit this scripts and remove the mysql dependency manually...but Why I must do it using this way? I wouldn't like to edit lot of rc scripts after every update. I am too lazy (and many admins too, I think) for doing this... For "daily" modifying are designed the configuration files, but not rc (and not only rc) scripts. I think that developers are able to edit this scripts, when is it needed, but not end-user. And I haven't see any reason to run mysql server localy, when all of applications are using external box as the database server. So, I looking for the another solution of this "problem". Any ideas about this "problem"? Thanks Tomas Krasnican
