Comment 2 for bug 274146

the issue has been discussed today at the desktop team meeting again, some of the options which are been listed:

* do nothing on upgrade and describe the change in the upgrade notes

* change the correspondance between applets and namespace on upgrade (ie migrates the session applet to the new fast user switching applet automatically), but that has side effects:

- that will break configuration for users which are using a fast user switch applet and no session applet for example
- users will not be able to use the upstream session applet if they want
- that will create use configurations which are ubuntu specific (some people run jhbuild session using the same profile for example)

* dynamically change the user configuration on upgrade or first login, that's something we didn't do until now and we have no good framework for it, it would require to writte a tool now and get it right

None of those is really good. I would not rush in changing namespaces or users configuration in upgrade. Does anybody else has a better idea about that?
