As far as I can tell there is no Gentoo-specific documentation for doing this, and from what I have read setting up NFSv4 is a PITA (perhaps that has changed in recent years). There are also use cases that don't involve NFS, such as containers. From the docs I have found on idmapd there wasn't actually a lot of detail, it wasn't clear if it "just works" without any specific configuration, perhaps it does. In any case, would it be that hard to set reasonable defaults? -- Rich
