There was two problems after update, but the first one ("umount: /mnt/library mount disagrees with the fstab") can be easily solved by the trailing slash. The reason why I mentioned it here is that it may be useful to know that it came along with the main unsolved problem with the "user" option ("umount: only root can unmount liveserv:/mnt/library/ from /mnt/library"). So the problem is related to "user" option.

Is the problem related to the "user" option or regarding a trailing "/"? wrt /etc/mtab being a symlink to /proc/mounts: I assume mount.nfs is built against libmount, seeing  as fixed? Do you get a file /run/mount/utab when the nfs share is mounted? What does it contain?  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626478
