It is called automatically without any parameters during startup and shutdown of the system. This ensures that .Xr showmount 8 does not display old and expired entries. The .Nm utility is only needed on client side, where .Xr mount_nfs 8 adds a mount entry with the current date to .Pa /var/db/mounttab , and .Xr umount 8 removes the entry again. The .Nm utility cares about all remaining entries in this table which result from crashes or unproper shutdowns. .Pp The options are as follows: .Bl -tag -width indentxxx .It Fl e Ar expire All entries which are not actually mounted or older than .Ar expire (seconds) are removed from .Pa /var/db/mounttab . This may be the case for DNS changes or long out of service periods. Default expire time is 86400 seconds (one day). .It Fl h Ar host Only remove the specific hostname. Send a UMNTALL RPC to the NFS server. .It Fl k Keep entries for existing NFS file systems. Compare the NFS file systems from the mounttab against the kernel mountlist and do not send the RPC to existing mount entries. Useful during startup of the system. It may be possible that there are already mounted NFS file systems, so calling RPC UMOUNT is not a good idea. This is the case if the user has rebooted to 'single user mode' and starts up the system again. .It Fl p Ar path Only remove the specific mount-path. Send a UMOUNT RPC to the NFS server. This option implies the .Fl host option. .It Fl v Verbose, additional information is printed for each processed mounttab entry. .El .Sh FILES .Bl -tag -width /var/db/mounttab -compact .It Pa /var/db/mounttab mounted nfs-file systems .El .Sh SEE ALSO .Xr mount_nfs 8 , .Xr mountd 8 , .Xr umount 8 .Sh HISTORY The .Nm utility first appeared in .Fx 4.0 . .Sh AUTHORS .An Martin Blapp Aq Mt mb@imp.ch
