Setting it to 'Y' so that the NFS client starts by trying to use numeric u/gids with 'sec=sys' should be safe, since we automatically fall back to using string-based owner/group names if the server rejects numeric values. Also note that older Linux servers return NFS4ERR_BADNAME in cases where they should be using NFS4ERR_BADOWNER: please can distribution maintainers make sure that they have applied commit f6af99ec1b261e21219d5eba99e3af48fc6c32d4 (nfsd4: name->id mapping should fail with BADOWNER not BADNAME).
