Hi,
please include in the top-level README.md a link where to download from sys-fs/eudev/ files: eudev-$num.ebuild, metadata.xml and the Manifest. It would be helpfull to those who don't have the files anymore in the portage tree. If the preferred way is to add some overlay, like without-systemd, please make it clear. Although I think providing the few files is safer.
Thank you,
