- Specify logical mount points within the
- namespace. See commentary below. _l_o_c_a_l-_n_a_m_e
- is the sub-mount point relative to /_p_r_e_f_i_x.
- _r_e_m_o_t_e-_n_a_m_e is an absolute path specifying the
- Sprite remote link.

- NNffssmmoouunntt is a pseudo-filesystem server that provides access
- to a remote NFS file system. The first argument is a host
- name, a separating colon (`:'), and a file system on that
- host. The second argument is a Sprite prefix under which
- the remote file system will be visible. The server is still
- very simple, although quite functional. Each operation
- causes an RPC to the remote host; there is no caching yet.
-
- Real NFS allows one filesystem to be mounted onto another
- NFS filesystem. This doesn't work in Sprite because Sprite
- requires a remote link (see ln command) for each NFS
- filesystem and it is not possible to create one of these
- within the parent NFS filesystem. Consequently, the subsidi-
- ary filesystem must be mounted elsewhere in the Sprite tree.
- Then the parent nfsmount program must be told that there is
- a logical mount point within its namespace using the -m
- option. The first argument is the name (relative to the
- root of the parent tree) where the mount point logically
- exists. The second parameter is the absolute path of the
- remote link where the child NFS tree is really mounted in
- Sprite.

- The ggeettppwwdd(()) library call doesn't work yet because it can't
- find the ``inode'' number of the prefix correctly. This is
- fixable but may not happen right away. A related problem is
- that the ddff command won't report disk space.
