ubuntu backport on launchpad usage

[Olivier Sallou <olivier.sallou@irisa.fr>]

Hi,
I have 2 questions on ubuntu backport on debian-med launchpad:

1) can we put a package, simply to get it available on current ubuntu
version? (though deb package will be available on next ubuntu release).
If yes, how do we manage it from version point of view ? If debian
package has version xxx-2, on launchpad we should put xxx-2~lucid1 ?

2) How do we manage  changelog. Should we update svn changelog of the
package to add a ~lucid1 (for example) in the history then send the
package to launchpad, or should we get the source code, create a
specific changelog for launchpad and then send the package?

Thanks

Olivier
