Well i've diggen around to understand that issue but fail to even catch the nvidia doc spirit: what is already deprecated or not ?
http://docs.nvidia.com/deploy/driver-persistence/index.html

their main comments:

NVIDIA will support both solutions for the near future (likely through
Cuda 6.0), but will focus all future development and bug fixes on the
daemon.

The daemon is installed in /usr/bin, while sample installation and init
scripts are included with the driver in the documentation directory. The
scripts are provided as a guide for installing the daemon to run on
system startup for some common init systems; they may require some
changes for certain distributions, due to the wide variety of init
system configurations.

NVIDIA encourages customers to shift to this daemon approach at their
earliest availability.

So is our kernel is using the 'legacy or 'daemon'  nowadays ?

Title:
  [346.59]  nvidia-persistenced journalctl errors

Status in nvidia-graphics-drivers package in Ubuntu:
  Confirmed

Bug description:
  vivid i386 booted with systemd 218-5ubuntu2, nvidia 346.35 & vivid
  genuine xorg/xserver

  346.35 dependencies are set to conflict with nvidia-persistenced

  /usr/share/doc/nvidia-346/html/nvidia-persistenced.html tell how to install it, but it fails into a terminal:
  oem@u32:~$ % nvidia-persistenced
  bash: fg: %: no such job
  http://us.download.nvidia.com/XFree86/Linux-x86/346.35/README/nvidia-persistenced.html

  and journalctl log:
  janv. 25 08:04:31 u32 kernel: NVRM: loading NVIDIA UNIX x86 Kernel Module  346.35  Sat Jan 10 20:33:56 PST 2015

  janv. 25 08:04:32 u32 nvidia-persistenced[424]: Shutdown (424)

  So some package(s) seems needing update; maybe needs to open xorg,
  xserver and/or systemd affected package(s) too.
