|
.Tn NFS
|
|
file systems mounted
|
|
on the host.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
utility first appeared in
|
|
.Bx 4.4 .
|
|
.Sh BUGS
|
|
The mount daemon running on the server only has an idea of the actual mounts,
|
|
since the
|
|
.Tn NFS
|
|
server is stateless.
|
|
The
|
|
.Nm
|
|
utility will only display the information
|
|
as accurately as the mount daemon reports it.
