I agree it's voodoo - but without setting up the file systems in
advance on the separate drives, when I tried to do the newfs on the ccd
mirrored drive all I got was "error 22 ioctl (CCDIOCSET) on component
0". This was the only way I found to make it work.

No argument there. I was avoiding raidframe only because I'm an OpenBSD
newbie (w/lots of Linux experience) and I was trying to find a solution
that would still allow me to use the stock/generic kernel for now.
After some more experience I'll look at switching to raidframe.

Certainly the kernel panics I got in the initial failed attempts to
make ccd work don't promote a sense of high confidence and
well-being....
