I meant to put a "LOL" after the comment about the huge thread.  I'm not
sure how I missed that.  :/   I did get it to work finally.  It took
several peoples help and a hammer on my part.  ;-)

I'm just curious as to how they are going to support this in the future.
 I have read where some say it can be done but others say it can't, or
not easily.  Old saying, this is where the rubber meets the road.  ^_^


To the OP.  I would use dracut.  I ran into trouble but I found out
later that a earlier attempt at a init thingy was causing the dracut
init thingy to mess up.  I strongly suspect that if I had known to get
rid of the previous attempt, it would have worked the first time.  My
previous attempt was the one that was built into the kernel itself.
Lets just say there was a huge fight and I missed it.  Grub was telling
one thing to load and the kernel was trying to load something else.  I'm
sure it was a nice fight.
