docker-initunlocklnd.sh:107
- This durable file contains the plaintext wallet password, but ordinary redirection creates it using the process umask (commonly mode 0644). That exposes the credential to other users in the container and also contradicts the new mode-600 assertion. Set a restrictive umask while creating it.

Inline comments:
In `@docker-entrypoint.sh`:
- Line 121: Update the WALLET_FILE/macaroons.db reset condition in the
entrypoint so it only sets the reset flag when macaroons are enabled; account
for no-macaroons=true in LND_EXTRA_ARGS, while preserving the existing wallet
and macaroon file checks for macaroon-enabled configurations.
In `@docker-initunlocklnd.sh`:
- Line 87: Update the payload construction in the unlockwallet call using
CANDIDATE so its Base64 value has wrapping newlines removed and its expansion is
quoted, preserving the complete wallet password in the JSON passed to post.
In `@docker-startup-tests.sh`:
- Around line 42-46: Align the docker startup test helpers and assertions with
the behavior actually implemented by docker-initunlocklnd.sh and the other
startup scripts: stop relying on the uncreated $WALLET.recovery record and
recovery-* fixtures, use the supported walletunlock.json/.newpassword layout,
update the password field that save_password() changes, and wait for log
messages those scripts emit instead of nonexistent readiness or failure strings.
- Line 5: Update the documented invocation to reference the root-level
docker-startup-tests.sh script, and correct its ROOT calculation so it resolves
the repository root from the script’s actual location. Ensure upgrade()
consequently mounts the repository’s docker-entrypoint.sh and
docker-initunlocklnd.sh paths.

I completed a static review of commits from You are interacting with an AI system. |

@coderabbitai so other than script not running automatically, no other complaints? The changes to docker-entrypoint.sh & docker-initunlocklnd.sh look good? I went with completely new approach, that includes both password change and macaroon rotation. |

This conclusion is from static review and shell syntax validation. I did not execute the Docker regression scenarios. Adding them to CI would provide runtime coverage for the new password-change and macaroon-rotation flow. 🐇🔍 ✏️ Learnings added
