Ah.... I see. I'm sure you could probably still do this somehow, but it'd
be a bit more custom, and may have drawbacks you do not want. For
example, perhaps have a script on startup pull down the package, or put
the RPM in a directory and then have a script install it. Neither is perfect.

If you have an online repo on something like the Open Build Service (OBS)
you should be able to point to it and pull in packages directly, though.
Is that something you have already tried? The UI where you choose which
SUSE/SLES software to install has an 'Add Repository' button or something,
and as long as the SUSE Studio servers can reach it I think you can use
it. If that's an option, you just need to be sure your package puts
things in the correct location by default.

Good luck.
