[wplug] Where the modules live

[Rick Reynolds]

I've always wondered how this works:  where is the path to the modules directory defined?

E.g., I build a kernel (say 2.4.2).  When I do the make_install, it places the modules under /lib/modules/2.4.2/...  Then, magically, the kernel knows where to get its modules from when it loads.  It seems like the definition of the modules directory is somehow "built-into" kernels when the get compiled.

I'd like to be able to change the path to something like "2.4.2-addDriver1" when I'm recompiling kernels to add certain features.  What I do now is rename the modules directory to something like "2.4.2-SAVE" and let the kernel build place the modules into the real location "2.4.2".  It would be nice if I could have multiple module paths, one for each of my kernels that I've built (especially when trying out new things).
