Keep in mind that different multiconfig does > not mean at all different basis (machine, distro, base image). Sorry, I am currently not that into the path structure of Isar. I just use the variables, but haven't looked at their values in detail. I thought, without checking, that the multiconfig name was part of some of those paths. Since multiconfigs select the kernels so they have to be part of the image name and maybe other paths as well to not cause conflict if multiple multiconfigs use the same machine and distro but different kernels.
