User namespaces are orthogonal to file systems, but anyway it looks like ZFS is refusing to let us do these things. I don’t have any great option to offer. You could perhaps modify run-in-namespace.c so that it doesn’t even try user namespaces and instead goes directly to the PRoot option? However working around this behavior of ZFS it not completely trivial and I’m not sure we should put much energy to paper over non-standard file system behavior. Thoughts? Ludo’.
