Yes, that seems to be the case.  Can you post the details of your network
configuration?

Also, can you reproduce this issue and then run 'killall -USR1 mountall'? 
This should trigger mountall to retry all pending network mounts.  I want to
rule out the possibility that the recent mountall changed introduced a
deeper problem with the mount handling.  (The race-the-network problem has
been reported before, so while it's new for you, it's not a new bug.)

Title:
  Mountall fails to mount NFS partitions on boot

Status in “mountall” package in Ubuntu:
  New

Bug description:
  NFS partitions fail to mount on boot, and mountall freezes without mounting them. If I revert this change to the init script:
       . /etc/default/rcS || true
       [ -f /forcefsck ] && force_fsck="--force-fsck"
       [ "$FSCKFIX" = "yes" ] && fsck_fix="--fsck-fix"

  + # Doesn't work so well if mountall is responsible for mounting /proc, heh.
  + if [ -e /proc/cmdline ]; then
  + for arg in $(cat /proc/cmdline); do
  + case $arg in
  + -q|--quiet|-v|--verbose|--debug)
  + debug_arg=$arg
  + ;;
  + esac
  + done
  + fi
       # set $LANG so that messages appearing in plymouth are translated
       if [ -r /etc/default/locale ]; then
           . /etc/default/locale || true
           export LANG LANGUAGE LC_MESSAGES LC_ALL
       fi

  - exec mountall --daemon $force_fsck $fsck_fix
  + exec mountall --daemon $force_fsck $fsck_fix $debug_arg
   end script

  it works. It seems strange that this would stop NFS from mounting on boot. It appears that the NFS mounts are occurring before DNS is up. mountall.log contains:
  mount.nfs: Failed to resolve server rt-ac66u: Name or service not known
  mountall: mount /mnt/readyshare [815] terminated with status 32
  Filesystem could not be mounted: /mnt/readyshare
  mountall: Disconnected from Plymouth
