Hi Anton,

In general, we want/need the rt kernels.

With the current state, I don't think Isar should be "fixing" this (e.g., by
automatically adding another deb repo providing the rt kernels), but instead
anyone wanting to use Trixie+rt at this time needs to address this downstream.

So for Isar, the question is just about how such builds would fail.
I guess the clean thing would be to correctly reflect what's there,
so remove the rt kernels from DISTRO_KERNELS and add them back once the packages
are provided by Trixie. Then builds trying Trixie+rt now would fail early in 
bitbake because "nothing provides linux-image-rt-amd64".

Or the dirty approach, ignore the problem, it should fix itself over time...
Then trying to build Trixie+rt now would fail when apt can't find linux-image-rt-*.

I think either way would be fine. Just maybe document that limitation.
