><i> OK. To backport from Cauldron to mga1, we have to backport from Cauldron to mga2,
</I>><i> (bumping the revision in cauldron to ensure that is is higher), then backport from mga2 to
</I>><i> mga1, ensuring that the revision is lower in mga1 than in mga2. (e.g. revision x.1 in
</I>><i> cauldron, x.0.1 in mga2, x.0.0.1 in mga1) Pretty straight forward.
</I>><i>
</I>><i> - Cherry-picking refers to the users' option to install a backport, which has nothing to
</I>><i> do with the packaging itself.
</I>><i>
</I>><i> - Ensure that upgrades never fail : Properly packaged, there is no reason why any
</I>><i> available backports will not install properly, as long as the tools are appropriately
</I>><i> adjusted. Backports should install just as reliably as regular updates.
</I>><i> Of course, if a particular backport or update is not available, it won't install.
</I>><i> Packages requiring it should not install either, which may not always be the case now.
</I>><i> (This should be verified - for backports and updates.)
</I>I see backports as the way to get some new stuff from cauldron before cauldron is fully
stable. There is no point to backport from cauldron to n-2 (mga1 at the moment). If the user
wants so much newer stuff s/he better upgrade to latest stable.
To not fail upgrade you must make sure that n-1 backports are not newer than n +n's updates.
You can't enable backports repo at upgrade time or it would upgrade all possible packages
from backports repo. I'm quite sure most users don't want that to happen! Cherry-picking for
me means that i can upgrade some packages from backports and then disable the repo. After
that i'm still able to upgrade to fully stable next release (w/o backports).
