depmod doesn't respect /etc/depmod.d/ubuntu.conf config

Binary package hint: module-init-tools

I use a custom driver for CDC ETHER device and have a conflict with a standard cdc_ether driver.
I put my custom_cdc driver into "/lib/modules/`uname -r`/extra" and run depmod, which according to man depmod.conf should make my custom_cdc driver to load with high priority then standard cdc_ether driver. But it seems that depmod doesn't take into account /etc/depmod.d/ubuntu.conf config when building modules dependencies and modules.alias. So cdc_ether driver is loaded first when I plug my divice, but if my custom_cdc driver is located in extra it should be loaded first.

Here is alias of my driver and cdc_ether driver:

custom_cdc usb:v148Ep0900d*dc*dsc*dp*ic02isc06ip00*
cdc_ether usb:v*p*d*dc*dsc*dp*ic02isc06ip00*

And here is udev event which loads driver by alias:

MODALIAS=usb:v148Ep0900d0001dc02dsc00dp00ic02isc06ip00
MODALIAS=usb:v148Ep0900d0001dc02dsc00dp00ic0Aisc00ip00

So my custom_cdc driver has more concrete alias which include particular vendor/device id, but for some reason cdc_ether still loaded instead of my driver. This is because depmod build incorrect modules.alias where custom_cdc located after cdc_ether.

In debian it works correctly, because depmod produce modules.alias file with custom_cdc in the first line.

From your bug report, it's impossible to tell why you think an "extra" directory is considered special - there's nothing special about it, and no mention in the man page

If you want "extra" to be special, you need to add it to the "search" line in /etc/depmod.d/ubuntu.conf

I've tried this and it didn't help, that's why I've created the bug - because depmod doesn't respect "search" line in /etc/depmod.d/ubuntu.conf.

I've also tried to use DKMS to install my custom driver. DKMS puts drivers into "updates/dkm", which has highest priority in /etc/depmod.d/ubuntu.conf, but it also doesn't help - depmod still generates modules.alias with my custom driver at the end of the list regardless of alias of my driver.
