Arch Linux

Description:
It would be useful build dkms modules (if dkms is available) before generating
initramfs, because they might be required in the initramfs.
In my case, I use the zfs-dkms module and have to do this manually before rebooting,
because otherwise I cannot mount my rootfs on the next run.
The dkms service does therefor not solve.
As this service is triggered at multi-user.target it might even has a race condition
with services depending on certain dkms modules (if somebody wants to start virtualbox at startup).
I see a use case, where someone do not want to load a certain module for a certain kernel version,
but this could be solved by blacklisting (most people want to use the dkms modules, they have installed anyway)
If the main kernel package would stick to this practice, other
kernel packages might follow, so dkms modules would be become usable across different kernel variants.
