It's actually simpler: nfs is the NFS client (that is, used for importing / ``mounting'' remote NFS file systems locally) and nfsd is the Hurd's NFS server, which exports to other machines the local file system using the NFS protocol. Indeed both fsys_getfile and file_getfh are only used for exporting-via-NFS purposes -- you can safely ignore that for now. (I don't know any details about that, but if I understand this correctly, the worst thing which not implementing them means is that a remote user (who is importing a Hurd machine's file system using NFS) won't be able to see any files served / translated by unionfs (and most of the other translators).) That aside, I have never used nfsd and don't know of anyone who has (during the last years). I do use nfs (as does Olaf, as he told), and it basically works. Regards, Thomas
