If you are using openrc (as I am) I would say you really don't want  
systemd installed at all.  I can't imagine any good coming from that.   
You do need eudev,  I also have elogind installed, but I'm not sure if  
it's absolutely required, or if I had some other reason for installing  
(possibly to get rid of consolekit?)
