93 The remote mount table is not changed.
95 Issues a command to the remote mountd declaring that
97 of its file systems have been unmounted.
98 This should be used with caution, as it removes all
99 remote mount entries pertaining to the local system, whether or not any
100 file systems are still mounted locally.

110 This is useful after the local hostname has been changed and rmtab entries
111 using the old name remain on a remote machine.
112 Unfortunately, most mountd's will not be able to successfully handle removal
113 of such entries, so this option is useful in combination with

184 a heuristic specific to SunOS is used to determine whether such a mount
185 is actual (replacing the string
189 and verifying the resulting path).
191 Symbolic links on the server will cause the path in the remote entry to differ
194 To catch those cases, a file system is also deemed mounted if its
196 mount point is identical to the remote entry.
197 I.e., on a SunOS diskless client,
198 .Pa server:/export/share/sunos.4.1.1
201 Since the local mount point is
203 as well this will be handled correctly.
205 There is no way to clear a stale entry in a remote
208 local hostname (or whatever reverse name resolution returns for it)
210 To take care of these cases,

219 calls can only be changed by recompiling.
