Alad [1] filed a deletion request for linux-aufs_friendly [2]: Obscured PKGBUILD, dead upstream patchset, EOL upstream version. Also maintainer comment: "For some time now, OverlayFS has been able to do everything I've been using AUFS for. I'll continue maintaining this, but I won't be using it myself and suggest that AUFS users take a look at the latest version of OverlayFS (which can do several branches, too)."
