NFS support

[nizsheanez]

Hi.
go version go1.3.1 linux/amd64

I runed 2 containers:

1. with application source code in volume.
2. with daemon (https://github.com/beego/bee) which listen changes of files in volumes (--volumes-from app_container)

in volumes (folder mounted by NFS), your library can see when i change files inside container, but when i change it from outside - no notifications.

I found out in https://docs.google.com/document/d/1xl_aRcCbksFRmCKtoyRQG9L7j6DIdMZtrkFAoi5EXaA/edit
that this problem with NFS is known, but "It is unclear how important that case is"

Suggest me please: Must i create ticket about it in Go bug tracker?

Hi Alexey. The lack of NFS support is a limitation of the underlying operating system.

One work around would be to fallback to polling, but we don't have polling support built into fsnotify (at least not yet). See https://github.com/go-fsnotify/fsnotify/issues/9.

Yes, NFS doesn't support this type of function. (And how would it, imagine 20 network computers updating 20 files on one NFS)
