I don't see this, but perhaps I'm too close to it. To me it would make
more sense to say that netroot= is the proper way to get a NFS root or
network device for root, and root=dhcp/root=nfs/root=nbd/root=iscsi etc
are the legacy ways.
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?
3) Support it but print deprecation warnings like Legacy nfsroot.txt.
This would be my choice; the DHCP (BOOTP) root-path=[server:]/root-path
formats have been around for decades. I seem to recall network booting a
SunOS 4.1.2 box using that back in 1993, and I'll bet it wasn't a new
feature then.
Some changes I'm thinking about would benefit from dropping the non nfs:
formats, as they wouldn't have a clean home otherwise, but I don't think
that is a good reason to drop them -- they are too easy to support.
"Too easy to support" does not necessarily mean we should support.
