A profile can also set a default current working directory via `defaultCwd`, profile like "RootUserNamespace" need to run from a directory owned by root. A profile can also have two identities (eg: "Fakeroot" profile), a host identity corresponding to user ID `hostUID` and a container identity corresponding to user ID `containerUID`.
