This is a meta package I created to prevent future mainline linux updates breaking zfs-dkms packages. zfs-dkms is closely tied to linux kernel versions and has a compatibility layer to add specific support for each major linux kernel release (e.g. "6.x").
So zfs-dkms has long been worried about linux kernel upgrades, a major upgrade could make dkms fail, and this happened a few times in the past since Arch is very edge on kernel version upgrades.
For users using zfs as root, this become critical if dkms is not noticed during "pacman -Syu". The system won't boot for next reboot.
This meta package will be updated for each zfs release, and updating the linux kernel version upperbounds accordingly.
