oswitch could detect the failure that and try with a new UID, but I don't know how will filesystem permissions work with a different UID.

And why is UID 1000 already taken up within container? Perhaps the image is already providing a default user? In which case, do we say it's not compatible with oswitch or try to work that out.

This is r-base
one of the most likely images to be used by biologists. so we need to support it...
