depmod is run at the %post (and %postun) step from the kmod produced by akmod:
rpm -q kmod-nvidia-$(uname -r)-367.44-1.fc24.x86_64 --scripts

I remember that when using the fedup (fedora upgrade tool), there is a
need to run depmod because of some races conditions
(fedup doesn't wait for the posttrans task to finish and might reboot
right after,but before akmod will then install the produced kmod).

The current recommandation from fedup is to disable any kmod before fedup.

It might be a might be interesting to implement some reboot locking
mechanism in this case.
