retrieved from the back file system. The default value is
30 seconds.

EXAMPLES
The following example CacheFS-mounts the file system
server1:/user2, which is already NFS-
mounted on
/usr/abc as /xyz.
example# mount -F cachefs -o backfstype=nfs,backpath=/usr/abc,
cachedir=/cache1 server1:/user2 /xyz
The lines similar to the following appear in the /etc/mnttab file after the mount command is executed:
server1:/user2 /usr/abc nfs
