Booting with OpenRC works but there are some warnings.

GRUB2
Code:
linux   /boot/vmlinuz-4.12.3-gentoo-b6 root=/dev/sda2 rootfstype=ext4 init=/sbin/openrc-init ro quiet libata.force=noncq


rc-update show sysinit
Code:
         
                devfs | sysinit
                dmesg | sysinit
    kmod-static-nodes | sysinit
                sysfs | sysinit
                 udev | sysinit
         udev-trigger | sysinit


Warning 1: "md5sum is missing, which suggests /usr is not mounted"
Warning 2: "/dev/null: Read-only file system"
Warning 3: "fopen('/run/openrc/rc.log') no such file or directory"

Question 1: How do I keep the sysinit runlevel messages on console?
Question 2: How do I use "openrc-shutdown" as normal user?

You mean the kernel is clearing the console?
I think maybe switching framebuffer from efifb to radeondrmfb causes this.

you said your sysinit messages were getting cleared. you meant your console gets cleared before login? that's done by agetty. man agetty and /etc/agetty.

*sigh* looks like you got hit by a troll. Let's try this again.

Run agetty with --noclear. It sounds like you're not using standard init so that goes in /etc/conf.d/agetty.

Normally you'd not do that, instead run acpid and use the physical power button to run shutdown. But here you'll either have to edit /etc/acpi/actions/powerbtn.sh or make a openrc-shutdown -> shutdown symlink.

For console:
OpenRC logging doesn't work for sysinit runlevel and I want to see all boot messages from init to login.
I see the OpenRC messages for sysinit runlevel, but then the screen is cleared (goes blank), then I see the boot and default runlevels messages, then the login prompt (agetty "--noclear" is set).
So does OpenRC clear the console after sysinit or is it because of the framebuffer switching from efi to radeon or is something else?

For shutdown:
openrc-shutdown allows only root to use it
Code:
   if (geteuid() != 0 && ! do_dryrun)
      eerrorx("%s: you must be root\n", applet);

So sudo or setuid are the only options I see here.

One one of my systems it does. Maybe due to using an initramfs which is needed for lvm2.

Maybe, from rc.conf:

# NOTE: Linux systems require the devfs service to be started before
# logging can take place and as such cannot log the sysinit runlevel.
