make.conf MODULES_OVERRIDE =?

From where I get the module names for MODULES_OVERRIDE when compiling the kernel?

man 4 re gives:

device miibus
device re

There is a directory re in /usr/src/sys/modules, but no miibus,
perhaps mi is the corrct one.

But I do not find anything for run(4), neither run, nor if_run, nor runfw, etc. What should I put in the variable?
And how do I get it?

Thanks !
 
And there is also a module snd_uaudio, but I also not know how to build it, what should I put in MODULES_OVERRIDE.

And it seems I also need uhid, but there is also no directory for it in /usr/src/sys/modules/.

UPDATE: uhid and run are in directory usb, uaudio in sound. Does thos mean that paths are allowed values for MODULES_OVERRIDE?
 
I am pretty new to FreeBSD, but MODULES_OVERRIDE seems to accept the paths, specifically the relative directory paths under /usr/src/sys/modules. For instance, mine (/etc/make.conf) looks like:

Code: 
MODULES_OVERRIDE= \
        cpuctl \
        drm2/drm2 \
        drm2/i915kms \
        ext2fs \
        fusefs \
        i2c/controllers/ichsmb \
        i2c/smbus \
        iwm \
        iwmfw/iwm7265Dfw \
        linuxkpi \
        tmpfs \
        usb/uhid \
        usb/ums \
        usb/wmt \
        wlan_ccmp \
        wlan_tkip \
        wlan_wep

I found out this by encountering/fixing errors while running make buildkernel. It would be nice if this was clearly documented in the handbook.

After building the kernel, /boot/kernel has become significantly lighter:

I think yours needs to look like:

Code: 
MODULES_OVERRIDE = mii usb/uhid sound/driver/uaudio ...
