In my Linux Yocto-base distribution is not installed the file sysctl.conf by the procps recipe

Discussion category: Systemd, Yocto, Sysctl

Additional information:

On my Linux Yocto-base distribution, I encountered an issue where the file sysctl.conf was not installed. To verify this, I executed the command find / -name "sysctl.conf" which returned an empty output, indicating that the file was not present in the system.

Understanding the procps recipe

The procps recipe in Yocto is responsible for installing various system utilities, including sysctl. However, it appears that the recipe is not installing the sysctl.conf file by default. This file is crucial for configuring system parameters and is typically installed by the procps recipe in other Linux distributions.

Why is sysctl.conf not installed?

There could be several reasons why the sysctl.conf file is not installed in your Yocto-base distribution. Here are a few possible explanations:

Recipe configuration: The procps recipe might be configured to exclude the sysctl.conf file from installation. This could be due to a specific configuration option or a patch applied to the recipe.
Package dependencies: The sysctl.conf file might be part of a separate package that is not installed by default in your Yocto-base distribution. This package could be a dependency of another package, but not installed explicitly.
Customization: Your Yocto-base distribution might have been customized to exclude the sysctl.conf file from installation. This could be done intentionally to simplify the system configuration or to avoid conflicts with other packages.

Troubleshooting the issue

To troubleshoot this issue, I tried the following steps:

Check the recipe configuration: I examined the configuration of the procps recipe to see if it was excluding the sysctl.conf file. However, I couldn't find any evidence of this.
Verify package dependencies: I checked the package dependencies of the sysctl package to see if it was relying on another package that was not installed. However, I couldn't find any dependencies that were not met.
Customization check: I checked the customization of my Yocto-base distribution to see if it was intentionally excluding the sysctl.conf file. However, I couldn't find any evidence of this.

Resolving the issue

After troubleshooting the issue, I decided to try a few different approaches to resolve the problem:

Rebuild the procps recipe: I rebuilt the procps recipe to see if it would install the sysctl.conf file by default. However, this didn't resolve the issue.
Install the sysctl package manually: I tried installing the sysctl package manually to see if it would install the sysctl.conf file. However, this didn't resolve the issue either.
Customize the sysctl.conf file: I decided to create a custom sysctl.conf file to configure the system parameters. However, this required me to manually configure the file and ensure that it was being read by the system.

Conclusion

In conclusion, the sysctl.conf file was not installed by the procps recipe in my Linux Yocto-base distribution. After troubleshooting the issue, I tried a few different approaches to resolve the problem, including rebuilding the procps recipe, installing the sysctl package manually, and customizing the sysctl.conf file. While these approaches didn't resolve the issue, they did provide valuable insights into the configuration and customization of the Yocto-base distribution.

Recommendations

Based on my experience, I recommend the following:

Check the recipe configuration: Before troubleshooting the issue, it's essential to check the recipe configuration to see if it's excluding the sysctl.conf file.
Verify package dependencies: It's crucial to verify the package dependencies of the sysctl package to ensure that they are met.
Customization check: It's essential to check the customization of the Yocto-base distribution to see if it's intentionally excluding the sysctl.conf file.
Create a custom sysctl.conf file: If the sysctl.conf file is not installed, it's recommended to create a custom file to configure the system parameters.

Future work

In the future, I plan to investigate the following:

Recipe configuration: I plan to investigate the recipe configuration to see if it's possible to modify it to include the sysctl.conf file.
Package dependencies: I plan to investigate the package dependencies of the sysctl package to see if it's possible to modify them to include the sysctl.conf file.
Customization: I plan to investigate the customization of the Yocto-base distribution to see if it's possible to modify it to include the sysctl.conf file.
