There is no autodetection with 1.1. Once you have mdadm.conf you have
pretty hard rules about what to look for and how to assemble it - ie.
there is not much left to "auto" detect. Real autodetection would mean
there is _no_ such information available, and you figure out everything
by just looking at the devices you find.

And also causes much more pain when you install machines on an internal
network where it gets a random name (in fact all new machines get the
same temporary name), then it is moved to its real location and
reconfigured with its real name. And you wonder why your arrays aren't
assembled any more...
