I don't really understand your comment, I'm afraid.  Anyway:  Even with
my static address setup there's a 1:5 chance that the home directory is
not mounted in time.  If I wait for DHCP, it is never mounted in time.
Then, the boot process simply fails, which mustn't happen.

I agree that mounting the home directory via NFS is a rare configuration
nowadays but it is useful in some situations as has ever been supported
by UNIX-flavoured systems, so I think Ubuntu should support it, too.

At some point in the boot process, the boot process must not continue
until all fstab mounts have been successful (of course, with a proper
timeout).  Currently, the NFS error is simply ignored and the mounting
is postponed.  In my opinion this is suboptimal behaviour.

Title:
  nfs not mounted during boot

Status in “nfs-utils” package in Ubuntu:
  New

Bug description:
  I mount my home directory via NFS from a server.  I boot directly into
  my account, so no login is necessary.  But then, my home directory is
  not yet mounted.  However, if I switch from DHCP to static IP, it is
  mounted properly.  Thus, network is setup too late in the boot
  process, so that NFS fails.

  Client: Ubuntu 12.04

  Line in /etc/fstab:
  192.168.178.24:/home/bronger /home/bronger nfs rsize=8192,wsize=8192,timeo=14,intr   0   0

  Excerpt of *working*/etc/network/interfaces:
