MarsSeed [1] filed a deletion request for linux-slim [2]: Abandoned exact copy of AUR/linux-amd. Built with exactly the same make flags and config.x86_64 file. Both are targeting a newer -march=znver4 AMD microarchitecture. There is no reason to keep linux-slim. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/linux-slim/
