starting service order

[Sebastien ESTIENNE]

Hello,
I'm in the process to integrate monit in linux gentoo as the default way 
to handle system services.
I wanted to know if it was possible to define the order in which the 
services will start. for example mysql before apache. I think it's 
different from dependencies because sometimes only the order is important.
Maybe it could be implemented using dependency, if we could define that 
some dependency can fail.
thanks for your answers
