- pass in file system type through mount(2), and return this type in statvfs structures as generated by [f]statvfs(2); - align mount flags field with NetBSD's, splitting out service flags which are not to be passed to VFS; - remove limitation of mount ABI to 16-byte labels, so that labels can be made larger in the future; - introduce new m11 message union type for mount(2) as side effect.
