Gentoo: Migrate from systemd-utils[udev] to eudev

Update: Unfortunately, eudev has been removed from Gentoo because it isn’t maintained anymore. Switching to eudev is not possible anymore.

While eudev has been abandoned by the Gentoo maintainers in 2021, it has been picked up again by Alpine, Devuan and Gentoo contributors as an independent project. You can rather easily switch back to eudev, if you wish to do so.

First, unset the udev useflag of sys-apps/systemd-utils:

sys-apps/systemd-utils -udev

Second, emerge eudev and rebuild systemd-utils without adding them to the world tree (both in one command, otherwise it won’t work):

emerge --ask --oneshot sys-apps/systemd-utils sys-fs/eudev

Congratulations, you’re using eudev again 😉
