RE: iscsi: version number in draft 11

[Black_David@emc.com]

Julian,

 

The problem here is that I don't think the IESG regards them

as arbitrary.  Mark's message on this topic reveals the underlying

issue here:

>"ancient" iSCSI products that use version 0.

Resetting the version number gives vendors a very strong incentive to
update those products so that they'll interoperate.  The IESG has
little interest in helping out folks who have shipped products based
on Internet-Drafts (see the boilerplate introduction to every draft),
and to the extent that this is the motivation for playing games with
the version number, we're going to get a very poor reception.

David,

We could move to 10 when going RFC - version numbers are arbitrary anyhow.

Folks,

I've warned in the past that this use of version numbers
is going to cause problems, as it encourages the longevity
of obsolete implementations that don't interoperate.  Version
numbers should NEVER have been used for identification of
draft versions - in 20/20 hindsight a text key that could
have been dropped from the final RFC would have been better.

Prior guidance from the ADs has been that a version number
change from 0 to 1 in going to RFC would be ok.  Let's
reset the version number to 0, and anyone still using
something based on a draft from back when the version number
was still 0 has something truly ancient and is SOL.

Thanks,
--David
