While I don't care so much if the other legacy methods go into dracut, I 
might suggest strongly against including this one.  In addition to the 
other reasons:

* It was never used with DHCP root-path in the past.
* It relied on other hard-coded things that you don't see to specify the 
filesystem type and aufs/unionfs layering on top.  Note that it doesn't 
include filesystem type and mount options.
