[arch-general] Module needed by a unit

[Yamakaky]

Hi

I'm trying to improve the unit for a fan manager daemon for MacBook Pro. 
As it is, it's a dependency of multi-user.target. I would like it to 
start earlier in the boot process, so that he is available with 
rescue.target, and to refresh the computer during bootup.

I tried with DefaultDependencies=false and WantedBy=sysinit.target. The 
first time it is launched, he failed because the coretemp module isn't 
loaded. It's then restarted and all is OK, so I think the module is 
loaded between the two start. I would like it to start succesfully the 
first time.

Do you know how to fix this problem ? I thought about modules-load.d, 
but a dependency would be better.

Thanks
