Comment:
I'm open to that argument, but I think ZFS and nvidia are somewhat special cases; for example, `acpi_call-dkms` probably never needs to be folded into an initramfs image, so triggering a rebuild of them would be wasteful. Adding an opt-in trigger is a bit of a compromise (the downside, of course, is that the trigger order matters so we can't rely on `dkms_modules` to automatically insert `dkms` without breaking the ordering).
