Yes.

There's a RH bug open here:
https://bugzilla.redhat.com/show_bug.cgi?id=442958

I think this is very suitable to be abstracted.

First throws at a method:

GetDistroUpgrades()
::DistroUpgrade(type,distro_id,summary)

So, if we call GetDistroUpgrades() on Fedora 7, we get:

::DistroUpgrade(DISTRO_TYPE_STABLE,"fedora8", "Fedora Core 8")
::DistroUpgrade(DISTRO_TYPE_PRE_RELEASE,"fedora9rc1", "Fedora 9 RC1")
::DistroUpgrade(DISTRO_TYPE_UNSTABLE,"rawhide", "Fedora Rawhide")

These can be shown in a custom widget.

I'm not yet sure how to "do" the upgrade, maybe we have to proxy this to
the backend, or maybe we launch the process as the session user.

Other ideas welcome.

Richard.
