singularity requires suid components; it is not true unprivileged containers. singularity must be installed by an administrator of the system, binctr doesn't care about having privileged components installed. binctr is a lot smaller and more grass-roots as well, which could be good or bad. It's possible singularity wishes to also have truly unprivileged containers, but if that is one of its goals, it currently fails at it.
