DKMS uses the same method. There is where it SHOULD happen. The problem is that it's totally non-interactive and there's no notification to use user if it fails...

FWIW, the only reason I use akmods is for installation of the nvidia module when a new kernel is available.  I don't do auto updates so I simply check /var/cache/akmods/akmods.log to make sure I see something similar to....

22 Dec 10:05:25 akmods: Checking kmods exist for 3.12.5-200.fc19.x86_64
22 Dec 10:05:26 akmods: Building and installing nvidia-304xx-kmod
22 Dec 10:05:26 akmods: Building RPM using the command '/bin/akmodsbuild --target x86_64 --kernels 3.12.5-200.fc19.x86_64 /usr/src/akmods/nvidia-304xx-kmod.latest'
22 Dec 10:05:43 akmods: Installing newly built rpms
22 Dec 10:05:52 akmods: Successful.

is recorded when a new kernel is installed.
