OK, I was looking through the journal output and I think the key to the
lvm's not activating is the following:
4 12:54:57 ccs systemd[1]: Got notification message for unit
systemd-journald.service
4 12:54:57 ccs systemd[1]: systemd-journald.service: Got notification
message from PID 1750 (WATCHDOG=1...)
4 12:54:57 ccs systemd[1]: systemd-journald.service: got WATCHDOG=1
4 12:54:57 ccs systemd[1]: Received SIGCHLD from PID 2603 (lvm).
4 12:54:57 ccs systemd[1]: Child 2602 (lvm) died (code=exited,
status=5/NOTINSSTALLED)
4 12:54:57 ccs systemd[1]: Child 2603 (lvm) died (code=exited,
status=5/NOTINSSTALLED)
4 12:54:57 ccs systemd[1]: Child 2610 (lvm) died (code=exited,
status=5/NOTINSSTALLED)
4 12:54:57 ccs systemd[1]: Job
dev-mapper-linux\x2d\x2dfiles\x2dportage.device/start timed out.

So what is not installed?

Also, for the first two lines, I get hundreds of thatpair of lines, how
can I prevent such.
So, between the lvm problem and the udev renaming my eth0 devices these
are the key as to why things are going wrong -- with openrc udev is not
renaming eth0 at all.
