Our networking code bakes in a lot of assumptions about how networking should work - that CNI is *always* used with root, and that slirp4netns is *always* used only with rootless. These are not safe assumptions. This fixes one particular issue, which would cause CNI to also be run when slirp4netns was requested as root.

rootlessport needs to be enabled as well, when slirp4netns is used? Also, what is the usecase of this? |

I'm not honestly sure - support for slirp4netns as root was added at some point in the past, but I can't recall why. It doesn't seem to have many users. |
