What type of PR is this?

What this PR does / why we need it:

  • This PR fixes an issue with Azure Linux AKS GPU where an error takes place within the posttrans phase when installing the nvidia-container-toolkit RPM package. that causes /etc/nvidia-container-runtime/config.toml to not be generated in the OS. The reason of the failure is because nvidia-ctk, the binary used to generate the config file is missing. This is because nvidia-ctk is provided by the nvidia-container-toolkit-base RPM package and this RPM is installed after nvidia-container-toolkit. This PR thus changes the RPM installation sequence to satisfy the package runtime requirements.

lgtm I think, is this currently causing wide impact in prod? if so then it'd probably worth to cherry-pick this to master so it can roll out in next week's release

Can we add a comment to show this ordering is necessary

Were you able to find official Nvidia docs that mentioned about this ordering dependency?

I did not find any official doc that directly explains the dependency relationship between these packages. But a good source to refer to would be the official spec file for nvidia container toolkit: https://github.com/NVIDIA/nvidia-container-toolkit/blob/main/packaging/rpm/SPECS/nvidia-container-toolkit.spec where the runtime requirements explain the dependency.

This has not been causing impact in prod yet since no customer bug requests have been noticed, but there's a possibility that customer workloads might be impacted by this issue.
