Then the documentation should be updated to say this and point to Eucalyptus documentation and give any needed information on the upgrade path from UEC/Natty to Eucalpytus/Oneiric. I don't think just deleting UEC is the right change.

Is the documentation that was removed still valid even though UEC is obsolete? If the directions are going to cause problems, then it should be removed, even if no Ubuntu Cloud documentation is available yet.
Otherwise I think they should be updated to describe an upgrade path from UEC to Ubuntu Cloud as Scott suggested (whether this is done here or in the new chapter you are working on). Let's see if we can decide on an approach before String Freeze this coming week. Thanks.

Trying to answer a few of Connor's questions:
- No the docs are not valid since UEC as a whole no longer exists. So yes for 11.10 these docs would be meaningless, and IMO should be removed
- Ubuntu Cloud (new product based on openstack) docs will hopefully be made available before Oneiric release. I will be compiling most of it (however I am now blocked since the product itself is not exactly ready yet)
- AFAIK, there is no upgrade path from UEC to UC. This had been discussed at previous UDS, and since the two cloud products are based on completely different technologies (eucalyptus vs openstack) the upgrade story was too complex, and AFAIK does not exist
So IMO, old UEC docs should be removed. And perhaps a note should be added that "If you are using UEC, a product that shipped with earlier versions of Ubuntu server, you can view docs about it here <help.ubuntu.
Does that make sense?

That makes sense, Ahmed, thanks for posting back. Since we do not have system documentation available yet for Ubuntu Cloud, let's add a note that UEC is no longer available and post a link to online documentation about Ubuntu Cloud (even if it's still a placeholder). Right now I see http://

I'd like to see some guidance for existing UEC users, even if it's "Don't
upgrade because you're screwed if you do". Ideally there are Eucalyptus
packages in Oneiric that they can upgrade to use even if UEC as a product
isn't provided anymore. I don't think just rm -rf all mention of UEC is the
right thing to do.

I just checked and the server team is pretty confident eucalyptus will not be usable in 11.10, so the advice is pretty much going to be ""Don't upgrade because you're screwed if you do"
I'll add that warning, a link to the help.u.c UEC docs, a link to the natty serverguide and a link to the yet-to-be-written new ubuntu-cloud chapter in a later commit

Adding UEC deprecation warning
Revision history for this message
| Dave Walker (davewalker) wrote : | # |
Things have changed since the latest advice we provided we provided to Ahmed. With thanks to upstream, it seems to be functional. This being said, Eucalyptus hasn't received the same level of testing and QA that previous Ubuntu releases had. Therefore, I think it's reasonable guidance to suggest staying with Natty (where it is still in Main) - but upgrading /should/ work.
Thanks.

This merge proposal is obsolete is it not? Can it be set to "REJECTED" and deleted?
We are no longer edting oneric anyhow, and any good carry forward edits I think have been done. (line 61, for example)

There were a couple of single lines changes (43, 52) herein that I have added to an edit being done now for raring. As mentioned before the line 61 change has already been done. The rest is obsolete or already done, and this will be set to REJECTED to get it off the list.
