Files should come from packages where ever possible. Maybe just add
some 11-isar.conf in the package that we could call
"isar-ci-ssh-setup", that file can be shipped to debian as well ...
should not hurt.

And you would DEBIAN_DEPENDS on NM instead of installing it manually.
In the end the image would be

inherit isar-image-base
IMAGE_INSTALL += "isar-ci-ssh-setup"

Or we even just put that into the sample local conf and do not even
need another image. Maybe as a comment where only the testsuite
uncomments it, so users who build our examples do not get such "open
images"
