1-2: Consider using debhelper instead of direct systemctl callsAs mentioned in the PR objectives, the implementation directly uses systemctl. Consider using
deb-systemd-invokefor better Debian compliance.For proper Debian integration:
- Use
deb-systemd-helperfor systemd service management- Use
deb-systemd-invokeinstead of direct systemctl calls- Consider implementing this script using debhelper's
dh_installdebWould you like assistance in implementing these improvements?

1-1: Enhance script robustness with additional shell options.Add
-uflag to catch undefined variables and set POSIX mode explicitly.-#!/bin/sh -e +#!/bin/sh -eu +set -o posix
1-5: Consider additional Debian packaging best practices.To improve maintainability and reliability:
- Add proper maintainer script sections (configure, abort-upgrade, etc.)
- Use
set -ein combination with proper error trapping- Consider using
debhelperscripts where possible- Add logging to help diagnose installation issues
Example structure:
#!/bin/sh set -e # Source debconf library . /usr/share/debconf/confmodule case "$1" in configure) # Your existing code here, properly structured ;; abort-upgrade|abort-remove|abort-deconfigure) ;; *) echo "postinst called with unknown argument \`$1'" >&2 exit 1 ;; esac # Optional: use debhelper #DEBHELPER# exit 0pkg/deb/usr/lib/systemd/system/peerbanhelper.service (1)

1-2: Verify configuration file handling
Let's verify that the configuration files mentioned in the conffiles are properly handled during package removal.
✅ Verification successful
Configuration files are properly handled during package removal
The verification shows that:
- The conffiles correctly lists the configuration files:
/etc/peerbanhelper/config/config.ymland/etc/peerbanhelper/config/profile.yml - The postrm script correctly handles configuration files by:
- In purge mode: Removes entire
/etc/peerbanhelperdirectory - In remove mode: Preserves
configandscriptsdirectories while removing everything else
- In purge mode: Removes entire
- The configuration files are properly placed in the package structure at
/etc/peerbanhelper/data/ - The maintainer scripts follow the Debian policy for configuration file handling
The implementation ensures proper preservation of user configurations during package removal while allowing complete cleanup during purge operations.
🏁 Scripts executed
The following scripts were executed for the analysis:

4-4: LGTM: Dependencies are correctly specified.
The Depends line maintains the required dependencies with proper version constraints.
3-3: LGTM: Pre-Depends on adduser is appropriate.
The addition of Pre-Depends: adduser is correct as it ensures the required user management tools are available before package configuration.
Let's verify the user creation in the postinst script:
✅ Verification successful
Pre-Depends on adduser is correctly used and verified
The Pre-Depends: adduser is justified as the postinst script creates a system user using adduser command. This ensures the required user management tools are available before package configuration, which is essential for:
- Creating the system user 'peerbanhelper'
- Setting up proper ownership of /etc/peerbanhelper directory
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check if postinst script exists and uses adduser
if [ -f "pkg/deb/DEBIAN/postinst" ]; then
echo "Checking postinst for user creation..."
grep -A 5 "adduser\|useradd" pkg/deb/DEBIAN/postinst

The bot is pretty cool but I think I'm going to ignore all of the suggestions. The last suggestion (security hardening) is of course useful but is generally not done for other Debian packages and would require some futher testing. Feel free to add them yourself via |
|
I implemented the suggested changes but I haven't actually tested them because I'm still using v7.1.1. Also do you want me to research how to deal with the config changes or is it okay to break existing installations? How's the policy on that? |

8-8: Configure proper logging for the service.
The service lacks proper systemd logging configuration, which could affect log collection and management.
The previous suggestion about adding proper logging configuration is still valid:
+StandardOutput=journal
+StandardError=journal
+SyslogIdentifier=peerbanhelper
For migration we may check existing config in the post-install script and move them. The log change will be deployed in next patch, today night or tomorrow |
@Gaojianli I reject this suggestion: #698 (comment) |

Resubmitted as #732. |
Disclaimer: I'm not a Debian maintainer and I'm sure there are some edge cases not handled by the way I do the pre/post scripts (for example I call
systemctldirectly instead ofdeb-systemd-invoke) but this works for me. I'm sure this can be improved upon once submitted to/picked up from the Debian repo.Summary by CodeRabbit
