Comment 6 for bug 30594

This could be a pretty tricky issue to solve. While there are NFS mounts that might not be there any more when you resume from suspension/hibernation, there are also NFS mounts that are too important to unmount (might bring programs or even the whole system crashing down) that would probably reestablish themselves nicely if you left everything alone, connected and all.

Either way, I'm passing this onto the NFS people to decide. If there is a hook-script to unmount all NFS shares, it should be in the nfs-common package anyway. See /usr/share/doc/pm-utils/README.distributions for more information.

Perhaps we could ship a template hook script to /etc/pm/sleep.d that is disabled by default (chmod -x) that can be enabled and modified by the user.
