I don't have a Gentoo box in front of me to check, but I think udev and systemd can not be installed simultaneously. Was this changed? -- Joost

You could *try* to run systemd and see if you like it. Many of us do. For the option to try systemd, I would first require a detailed how-to on how to switch back to OpenRC without requiring reverting to backups or doing a full reinstall. You don't need to use backups, much less a full reinstall. However, several packages must be reemerged and a couple ones must be uninstalled before you switch to systemd. Obviously, you need to do the opposite to revert back to OpenRC. Which packages must be reemerged and which ones must be uninstalled depends on what do you have installed. It is mostly handled by portage, though, so you don't need to worry about it. If you unpack a stage3 tarball for a new installation, the only thing you need to do to get systemd is to emerge systemd and change your init line in your boot loader. Portage will uninstall udev for you, and OpenRC will remain, but it would do nothing. The more things you add to your system, the more packages will be affected by the change, in either direction. Also, systemd requires more kernel configure options enabled than OpenRC. To change back, usually you will only need to unemerge systemd, emerge udev, and perhaps USE=-systemd emerge -uDNvp @world. Be warned that the best thing to do is to do it from a LiveCD; if you boot with systemd, and uninstalled it, I don't think the shutdown would be clean.

[gentoo-user] Systemd as drop-in replacement for udev?
Hello all, I am currently updating my system and Portage wants to replace udev (204) with systemd (208). My question is (hopefully) simple: Can I use systemd as drop-in replacement for udev? In other words, can I pretend that systemd is udev and continue using OpenRC as with udev itself? I would then apply just udev 204 to 208 update instructions (http://wiki.gentoo.org/wiki/Udev/upgrade). I am using WindowMaker and systemd was pulled in by gnome-settings-daemon which in turn was pulled in by gdm. I would like to stick with gdm. Usually I feel pretty comfortable replacing one package with another if Portage wants so (e.g. because they block each other) but in this case I want to be extra careful. I did not find a clear answer to this. Usually people either migrate fully to systemd (replacing openrc) or stays with udev + openrc.

I did not find a clear answer to this. Usually people either migrate fully to systemd (replacing openrc) or stays with udev + openrc. I think that's the usual way; either switch completely to systemd, or keep using OpenRC+udev (or OpenRC+eudev, or several other combinations). The GNOME stuff that requires systemd will not work under OpenRC from 3.10 on, you could get strange fails with gdm and gnome-settings-daemon. If it's gdm-3.8, then I think you can use systemd as udev replacement together with OpenRC, and I believe some people did it successfully.

I have enabled openrc-force use flag found this in gnome-settings-daemon emerge log, which confirms what you have said: gnome-settings-daemon needs Systemd to be *running* for working properly. Please follow the this guide to migrate: http://wiki.gentoo.org/wiki/Systemd You are enabling 'openrc-force' USE flag to skip systemd requirement, this can lead to unexpected problems and is not supported neither by upstream neither by Gnome Gentoo maintainers. If you suffer any problem, you will need to disable this USE flag system wide and retest before opening any bug report. So the it is clear to me now. I will try openrc-force as temporal solution until I'll find a new display manager and give heart breaking good by to GDM.
