Done.

I see.

I don't understand.  *After* installing systemd (and setting the USE and
executing the emerge --newuse ...), the wiki tells you to 
   /etc/init.d/udev restart
Emerging systemd unmerges udev so how can I do the restart?

How far do I have to get in the wiki?  I am hoping to do smaller chunks
so that if I have to back out a step (using a bootable CD) to restore
"bootability" to the system, it won't take too long.

In particular do I have to switch init to /usr/lib/systemd/systemd
before I can boot.

I know you have had systemd installed for a long time.  Did you always
have the init= line or were you for a while running openrc with systemd
installed?

I am not so worried about gnome coming up.  If the system boots and I
can get the 6 text terminals, I can survive for quite a while with emacs
and gnus.

Again thanks for the help.
