  .Pp
+ If the option ``intr'' is specified for a
+ .Pa fs_vfstype
+ .Pa nfs
+ filesystem, the mount is considered interruptible, which implies
+ that file system calls that are delayed due to an unresponsive
+ server will fail with EINTR when a termination signal is
+ posted for the process.
+ .Pp
  If the option ``noauto'' is specified, the filesystem will not be automatically
  mounted at system startup.
