You need to edit src/libdiskfs/*.c to change
the access routines to add

        have = ino.mode&0777;
        if(ino.uid == au->uid)
                have >>= 6;
        else if(ino.gid == au->gid || ingroup(au, ino.gid))
                have >>= 3;
        if(au->uid == 0)        // <<< these two lines
                have = 7;
