Linux Patch API - Package Build Guide

This document provides comprehensive instructions for building production-ready Debian (.deb) and RPM (.rpm) packages for the Linux Patch API.

Prerequisites

For Debian Package Building

# Install required tools
apt-get update
apt-get install -y \
    cargo \
    rustc \
    debhelper \
    pkg-config \
    libsystemd-dev \
    dpkg-dev \
    fakeroot

For RPM Package Building

# Install required tools (RHEL/CentOS/Fedora)
dnf install -y \
    cargo \
    rust \
    rpm-build \
    rpmdevtools \
    systemd-rpm-macros \
    pkgconfig \
    systemd-devel \
    gcc

# Or on Ubuntu/Debian for cross-building
apt-get install -y \
    cargo \
    rustc \
    rpm \
    rpmbuild \
    libsystemd-dev

Building Debian Package (.deb)

Quick Build

cd /a0/usr/projects/linux_patch_api

# Build release binary
cargo build --release --target x86_64-unknown-linux-gnu

# Build Debian package
dpkg-buildpackage -us -uc -b

# Package will be created in parent directory
# linux-patch-api_1.0.0-1_amd64.deb

Detailed Build Process

# 1. Ensure release binary exists
cargo build --release --target x86_64-unknown-linux-gnu

# 2. Verify debian/ directory structure
ls -la debian/
# Should contain: control, rules, changelog, compat, install, conffiles, copyright
# And maintainer scripts: preinst, postinst, prerm, postrm

# 3. Build the package
dpkg-buildpackage -us -uc -b

# 4. Verify package contents
dpkg-deb --contents ../linux-patch-api_1.0.0-1_amd64.deb

# 5. Verify package info
dpkg-deb --info ../linux-patch-api_1.0.0-1_amd64.deb

# 6. Lint the package (optional but recommended)
lintian ../linux-patch-api_1.0.0-1_amd64.deb

Installation Test

# Install the package
dpkg -i linux-patch-api_1.0.0-1_amd64.deb

# Verify installation
systemctl status linux-patch-api
linux-patch-api --version

# Check installed files
dpkg -L linux-patch-api

# Remove package (keeping configs)
dpkg -r linux-patch-api

# Purge package (removing all configs)
dpkg -P linux-patch-api

Building RPM Package (.rpm)

Quick Build

cd /a0/usr/projects/linux_patch_api

# Build release binary
cargo build --release --target x86_64-unknown-linux-gnu

# Build RPM package
rpmbuild -ba linux-patch-api.spec

# Package will be created in ~/rpmbuild/RPMS/

Detailed Build Process

# 1. Set up RPM build environment
rpmdev-setuptree

# 2. Copy spec file to SPECS directory
cp linux-patch-api.spec ~/rpmbuild/SPECS/

# 3. Copy source tarball to SOURCES directory
# Create source tarball
tar -czvf linux-patch-api-1.0.0.tar.gz \
    --exclude=target \
    --exclude=.git \
    --exclude=debian \
    --exclude=*.deb \
    --exclude=*.rpm \
    .

mv linux-patch-api-1.0.0.tar.gz ~/rpmbuild/SOURCES/

# 4. Build the RPM
rpmbuild -ba ~/rpmbuild/SPECS/linux-patch-api.spec

# 5. Verify RPM contents
rpm -qlp ~/rpmbuild/RPMS/x86_64/linux-patch-api-1.0.0-1.el9.x86_64.rpm

# 6. Verify RPM info
rpm -qip ~/rpmbuild/RPMS/x86_64/linux-patch-api-1.0.0-1.el9.x86_64.rpm

# 7. Lint the spec file (optional but recommended)
rpmlint ~/rpmbuild/SPECS/linux-patch-api.spec

Installation Test

# Install the RPM
rpm -ivh ~/rpmbuild/RPMS/x86_64/linux-patch-api-1.0.0-1.el9.x86_64.rpm

# Or using dnf/yum
dnf install ~/rpmbuild/RPMS/x86_64/linux-patch-api-1.0.0-1.el9.x86_64.rpm

# Verify installation
systemctl status linux-patch-api
linux-patch-api --version

# List installed files
rpm -ql linux-patch-api

# Remove package
rpm -e linux-patch-api

Using the Interactive Installer

For manual deployment without package managers:

# Ensure binary is built
cargo build --release --target x86_64-unknown-linux-gnu

# Run installer (must be root)
sudo ./install.sh

The installer will:

Detect operating system
Check prerequisites (systemd, binary)
Create system user and group
Create directory structure
Install binary and configuration files
Install systemd service
Optionally generate self-signed certificates
Optionally enable and start the service

# Check for build errors
cat ~/rpmbuild/BUILDROOT/*/var/log/rpmbuild.log

Error: missing BuildRequires

# Install development packages
dnf install -y systemd-devel pkgconfig

Service Issues

Version Management

Updating Version for New Release

Update Cargo.toml:

[package]
version = "1.0.1"  # Increment version

Update debian/changelog:
```
dch -v 1.0.1-1 "Release notes here"
```

Update RPM spec:

Version:        1.0.1
Release:        1%{?dist}

Update ROADMAP.md:
- Mark previous version complete
- Add new version to changelog

Security Considerations

Packages are signed with maintainer GPG key for production deployments
All maintainer scripts run with set -e for fail-fast behavior
Configuration files are marked as conffiles to preserve user modifications
System user has minimal privileges (nologin shell, no home directory)
Directory permissions follow principle of least privilege
TLS certificates should be replaced with CA-signed certs in production
