hibernate + network file systems has always been a rather tough nut .
NFS is built on the fact that multiple clients may have the same tree
open at the same time... so if you are going to hibernate you are
going to need to basicallly unmount because there is no guarentee that
anything underneath you will be there when you come out of
hibernation.

inotify would only work if the server somehow was able to give
information back to the client over inotify.
