Please delete these packages as systemd units are included in respective (official) packages. https://aur.archlinux.org/packages/systemd-hiawatha-units https://aur.archlinux.org/packages/systemd-httpd-units https://aur.archlinux.org/packages/systemd-mysqld-units The 'nexus' package is outdated, there is 'nexus2' package (from the same packager), which is newer version of the same software. I posted comment on 'nexus2' that the package should be merged into 'nexus'. After the merge is done, 'systemd-nexus-units' can be deleted, 'nexus2' includes systemd service file. https://aur.archlinux.org/packages/nexus/ https://aur.archlinux.org/packages/nexus2/ https://aur.archlinux.org/packages/systemd-nexus-units/ What's the policy about packages containing only one systemd unit file? IMO such packages should not even exist, such content should be on wiki... Though I have nothing against collections of unit files (like 'user-session-units' package). I suggest these packages for deletion (really useless IMO): https://aur.archlinux.org/packages/systemd-network-units https://aur.archlinux.org/packages/wol-systemd
