I'm willing to consider dropping root=* and supporting only netroot= for 
NFS.

OTOH, Harald was thinking about extending the iscsi root-path syntax 
specification to allow for specifying the root device (by partition 
name, LABEL, UUID, etc.) within the root-path itself.  This might 
eliminate the need for a separate root=.

There may however be value in allowing an optional separate root=.  This 
might allow a mechanism for a bootloader menu to select a different root 
device during netboot.

Harald have you put further thought into the iscsi root-path syntax 
extension?

"Too easy to support" does not necessarily mean we should support.
