MarsSeed [1] filed a deletion request for zfs-dkms-rc [2]: Useless, broken prerelease package from 2021. Users should use either the stable zfs module, or a git package: - zfs-linux-git (master branch pkg for the 'linux' kernel) - zfs-utils-staging-git (latest version-specific prerelease/rc branch) [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/zfs-dkms-rc/
