78 The actuality of mounts is verified using the entries in

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

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

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