The code for this hook was removed in #3457 but it wasn't removed from the manifest. Remove it to avoid unnecessary execution of the hook.

Summary by CodeRabbit

  • Chores
    • Updated conditions for bootloader and image component hooks to streamline execution logic.
    • Simplified the condition for the [image.kernel] section to check only for "tryboot".

📝 Walkthrough

Walkthrough

The changes in this pull request involve modifications to the manifest.raucm.gtpl configuration file. The conditions for applying hooks to the bootloader and image components have been updated. Specifically, the condition for the kernel image now only triggers the post-install hooks when the BOOTLOADER variable is set to "tryboot", simplifying the previous condition that allowed for "grub" or "tryboot". The logic for the boot image remains unchanged, continuing to depend on the ota_compatible variable.

Changes

File Path Change Summary
buildroot-external/ota/manifest.raucm.gtpl Updated conditions for [image.kernel] hooks to only check for BOOTLOADER equal to "tryboot"; [image.boot] logic remains unchanged.

22-24: LGTM! The changes align with the PR objectives.

The modification correctly removes the kernel post-install hook execution for GRUB-based targets while maintaining it for tryboot targets, which aligns with the cleanup needed after the hook code removal in PR #3457.

Let's verify the relationship with PR #3457:

✅ Verification successful

Verification confirms the changes are correct and consistent

The verification confirms that PR #3457 indeed removed the GRUB-related kernel post-install hook code from rauc-hook. The current implementation in rauc-hook shows that post-install hooks are now only used for specific purposes:

  • RPi5 slot management
  • Yellow board CM5 support

The manifest change to only execute post-install hooks for tryboot is consistent with the current codebase state, as GRUB-based systems no longer need these hooks.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify that the hook code was indeed removed in PR #3457
# and that no other files still reference GRUB-related kernel post-install hooks

# Check the PR #3457 changes
gh pr view 3457 --json files

# Look for any remaining references to GRUB-related kernel post-install hooks
rg -l "grub.*kernel.*post-install|kernel.*post-install.*grub"

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

The hook is still needed so check_grubenv gets called no? 🤔

I don't think so, check_grubenv is called from install-check hook enabled in global [hooks] section.

Oh right, this is about post_install_kernel, which we only use for RPi 5/tryboot now. Make sense!
