Understanding INHERIT =+ "rm_work":

In Yocto Project’s local.conf or in a specific recipe file, INHERIT =+ "rm_work" is a directive that instructs BitBake to automatically include the rm_work functionality for all recipes. Here’s how it enhances your build process:

• Automated Cleanup: By setting INHERIT =+ "rm_work", BitBake will automatically add rm_work handling to each recipe’s task sequence. This means after each task execution (such as do_compile or do_install), BitBake will clean up unnecessary temporary files in the work directory.
• Simplified Maintenance: Automating rm_work reduces manual effort and ensures consistent cleanup across all recipes. It’s particularly useful in large projects where managing temporary build artifacts manually can be cumbersome and prone to errors.

Setting INHERIT =+ "rm_work"

To enable rm_work for all recipes, add the following line to your local.conf:

INHERIT += "rm_work"

This ensures that BitBake will include rm_work functionality by default for all recipes, optimizing storage usage without compromising build integrity.
