openclaw - 💡(How to fix) Fix boot-md hook re-runs BOOT.md on every gateway restart [1 comments, 2 participants]

Fix Plan

To address the issue, we will make boot-md idempotent by tracking its run state in a flag file. Here are the steps:

• Create a flag file, e.g., /var/lib/boot-md/initialized
• Modify BOOT.md to check for the existence of the flag file before running initialization logic
• If the flag file exists, skip initialization; otherwise, create the flag file after initialization

Example Code

# In BOOT.md
if [ -f "/var/lib/boot-md/initialized" ]; then
  echo "Already initialized, skipping..."
  exit 0
fi

# One-time initialization logic here

# Create flag file after initialization
touch /var/lib/boot-md/initialized

Alternatively, you can use a more robust approach using a lockfile:

# In BOOT.md
lockfile="/var/lib/boot-md/initialized"
if [ -f "$lockfile" ]; then
  echo "Already initialized, skipping..."
  exit 0
fi

# One-time initialization logic here

# Create lockfile after initialization
flock -x "$lockfile" true

Verification

To verify the fix, restart the gateway and check that BOOT.md only runs once. You can add logging statements to BOOT.md to confirm that the initialization logic is skipped on subsequent restarts.

Extra Tips

• Consider using a more robust storage mechanism, such as a database or a dedicated configuration file, to track the initialization state.
• If you choose to redesign boot-md to not be a startup hook, ensure that the initialization logic is still executed at the appropriate time, e.g., during the first run of the gateway.
