Just to expand a bit on the linked thread:

Gentoo now has support for creating the device nodes at boot time, in
the stable baselayout, which should be 1.11.12-r4 at this point.

To enable it, you need:

1. A proper /etc/raidtab or /etc/mdadm.conf (mdadm.conf preferred)
2. The mdadm tools emerged.
3. Add "md" to RC_VOLUME_ORDER in /etc/conf.d/rc.

The above should trigger then execution of
/lib/rcscripts/addons/raid-start.sh during startup which will create the
device nodes for you.

I did not know any of this before I posted regarding the RAID device
nodes in the linked thread...
