Yes, that's the plan.  I have no ETA yet for when this will happen, but
hopefully in the next month.

Title:
  nfs4 mounts hang in bootup with upstart starting rpc.gssd

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

Bug description:
  System 12.04.2 32 and 64bit. nfs4 with krb5/ldap authentication.
  No network-manager!

  A nfs4 mount results in a system hang, if rpc.gssd is started before rpcbind (portmap) and the filesystem is defined as:
  nfs4    sec=krb5....
  in /etc/init/gssd.conf the start condition is
     start on (started portmap
            or mounting TYPE=nfs4 OPTIONS=*sec*krb5*)

  So when the file system is defined as:   nfs4   sec=krb5
  upstart does not wait on portmap (rpcbind) and starts sometimes rpc.gssd before rpcbind. This lead to mounting errors and prevents the further bootup.

  My solution at the moment is to define the file systems as:
      ... nfs  vers=4,sec=krb5...

  which works at the moment.
  (I have also added 
      NEED_GSSD=yes
      NEED_IDMAPD=yes
  to /etc/defaults/nfs-common
