Bug#928497: Acknowledgement (nvidia-persistenced: Error in nvidia-persistenced source (postinst))

Using the Debian Stretch plus SID Source repository and satisfying all the
dependencies required for a build, everything happens perfectly.
The installation of the packages after the compilation is perfect, the
modules work correctly.
However, in my first compilation of the nvidia-persistenced package without
any modification, I had an error that causes the
"nvidia-persistenced.service" service to not work.

Compilation method:

sudo apt-get -b source nvidia-driver nvidia-settings nvidia-modprobe
nvidia-settings nvidia-support glx-alternative-nvidia init-system-helpers
nvidia-persistenced

Installation response via apt (I've created a local repository to
facilitate):

Note: I tested the installation on a VM, since I already have a distro with
the functional driver

exited with error code.
See "systemctl status nvidia-persistenced.service" and "journalctl -xe" for
details.

Checking service status:

Verifying further details:

However, when checking if the package is installed:

stretch at debian:~$ dpkg -l libnvidia-cfg1* | grep ^ii
ii  libnvidia-cfg1:amd64 418.56-2     amd64        NVIDIA binary OpenGL/GLX
configuration library

Recompiling manually by removing the line containing the "--no-create-home
\" code from the files:

rm -rf nvidia-persistenced*.deb
cd `ls -d */ | grep nvidia-persistenced`
sed -i "/--no-create-home/d" `find . -type f -a -exec grep -l
"\-\-no-create-home"  '{}' \;`
cd -
dpkg-scanpackages -m -t deb . | sudo gzip -c > "$BDIR"Packages.gz
sudo apt-get update
sudo apt-get install --reinstall nvidia-persistenced

...
Configuring nvidia-persistenced (418.56-1) ...
Job for nvidia-persistenced.service failed because the control process
exited with error code.
See "systemctl status nvidia-persistenced.service" and "journalctl -xe" for

...

Note 2: This error that occurred was due to the VM because you do not have
the NVidia card in it, but note that the following error disappears:

Alert: The home directory /var/run/nvpd/ you specified can not be accessed:
No such file or directory
Not creating personal directory '/var/run/nvpd/'.

The NVidia driver compiled and installed on my actual machine contains the
following information:

dpkg -l nvidia-persistenced* | grep ^ii
ii  nvidia-persistenced 418.56-1     amd64        daemon to maintain
persistent software state in the NVIDIA driver

While testing the builds, I noticed that the repositories were updated on
"2019-05-06 23:23". The compilation I made, where I specified the missing
"/var/run/nvpd/" folder was made in "2019-05-05" and today when I did a new
build without modifying anything, it worked correctly.

I noticed that what I compiled for the first time,
"nvidia-persistenced.service" was specifying the folder in "ExecStart", so
the error occurred. Now it is not specified:

[Unit]
Description=NVIDIA Persistence Daemon
Wants=syslog.target

[Service]
Type=forking
ExecStart=/usr/bin/nvidia-persistenced --user nvpd
ExecStopPost=/bin/rm -rf /var/run/nvidia-persistenced

[Install]
WantedBy=multi-user.target

Now the compiled package is working normally, which means that the error I
mentioned is already fixed. However, you should be very careful when
choosing which packages to use for it so that it is as stable as possible.
