Hi,                                                                                             
                                                                                                
When I raised the bug initially, if I attempted to manually start the nvidia-persistenced service it *would* fail, attempting to write something into /var/run/nvpd/ which did not exist.

My apologies for not pasting the exact error message, I no longer have the log that far back and can't seem to reproduce it.  I see now that the intention is for the runtime info directory to be /var/run/nvidia-persistenced/ which is being correctly created at present.

I will only guess that what I saw was an absolute first-run quirk perhaps the result of a systemd (then systemd-sysv=252.26-1~deb12u2) default behaviour.

I still have the same/latest bookworm version of nvidia-persistenced installed, but have since upgraded most other nvidia-related packages according to bookworm-backports.

Scott.
