intr

nointr

(default: intr)

Specify intr if users are not likely to damage

critical data by manually interrupting an NFS

request. If a hard mount is interruptible, a user

may press [CTRL]-C or issue the kill command

to interrupt an NFS mount that is hanging

indefinitely because a server is down.

Specify nointr if users might damage critical

data by manually interrupting an NFS request,

and you would rather have the system hang while

the server is down than risk losing data between

the client and the server.

fg (foreground)

bg (background)

(default: fg)

Specify fg for directories that are necessary for

the client machine to boot or operate correctly. If a

foreground mount fails, it is retried again in the

foreground until it succeeds or is interrupted. All

automounted directories are mounted in the

foreground; you cannot specify the bg option with

automounted directories.

Specify bg for mounting directories that are not

necessary for the client to boot or operate

correctly. Background mounts that fail are retried

in the background, allowing the mount process to

consider the mount complete and go on to the next

one. If you have two machines configured to

mount directories from each other, configure the

mounts on one of the machines as background

mounts. That way, if both systems try to boot at

once, they will not become deadlocked, each

waiting to mount directories from the other. The

bg option cannot be used with automounted

directories.
