+## Building Arch Package (.pkg.tar.zst)
+
+### Quick Build
+
+```bash
+cd /path/to/linux_patch_api
+
+# Build release binary
+cargo build --release
+
+# Build Arch package
+chmod +x build-arch.sh
+SKIP_CARGO_BUILD=1 ./build-arch.sh
+
+# Package will be created in releases/
+ls -la releases/*.pkg.tar.zst
+```
+
+### Detailed Build Process
+
+```bash
+# 1. Install build dependencies (Arch Linux)
+sudo pacman -Syu --noconfirm rust cargo systemd git base-devel gcc
+
+# 2. Build release binary
+cargo build --release
+
+# 3. Run build script
+chmod +x build-arch.sh
+./build-arch.sh
+
+# 4. Verify package contents
+bsdtar -tf releases/linux-patch-api-*.pkg.tar.zst
+
+# 5. Verify package info
+pacman -Qi releases/linux-patch-api-*.pkg.tar.zst
+```
+
+### Install Script Hooks
+
+The Arch package includes an `.install` file (`configs/linux-patch-api.install`) that runs automatically on install:
+
+- **post_install**: Creates directories, copies example configs, enables systemd service
+- **post_upgrade**: Reloads systemd daemon
+- **pre_remove**: Stops and disables service
+- **post_remove**: Cleans up empty directories
+
+### Installation Test
+
+```bash
+# Install the package
+sudo pacman -U ./releases/linux-patch-api-*.pkg.tar.zst
+
+# Verify installation
+systemctl status linux-patch-api
+linux-patch-api --version
+
+# Check installed files
+pacman -Ql linux-patch-api
+
+# Verify config files exist
+ls -la /etc/linux_patch_api/
+
+# Remove package
+sudo pacman -R linux-patch-api
+```
+
+**Note:** The build script creates a `builduser` for `makepkg` when running as root (typical in CI environments). The `.install` hook handles directory creation, config copying, and service enablement.
+
+## Building Alpine Package (.apk)
+
+### Quick Build
+
+```bash
+cd /path/to/linux_patch_api
+
+# Build release binary (MUSL target for Alpine)
+cargo build --release --target x86_64-unknown-linux-musl
+
+# Build Alpine package
+chmod +x build-alpine.sh
+SKIP_CARGO_BUILD=1 ./build-alpine.sh
+
+# Package will be created in releases/
+ls -la releases/*.apk
+```
+
+### Detailed Build Process
+
+```bash
+# 1. Install build dependencies (Alpine Linux)
+apk add --no-cache alpine-sdk rust cargo openssl openssl-dev elogind-dev musl-dev abuild gcc
+
+# 2. Add Rust MUSL target
+rustup target add x86_64-unknown-linux-musl
+
+# 3. Build release binary
+cargo build --release --target x86_64-unknown-linux-musl
+
+# 4. Run build script
+chmod +x build-alpine.sh
+./build-alpine.sh
+
+# 5. Verify package contents
+apk verify releases/*.apk
+
+# 6. List package contents
+tar -tzf releases/*.apk
+```
+
+### Install Script Hooks
+
+The Alpine package includes an install script (`configs/linux-patch-api.apk-install`) that runs automatically on install:
+
+- **pre_install**: Creates directories, sets ownership and permissions
+- **post_install**: Copies example configs, adds service to default runlevel
+- **pre_deinstall**: Stops and removes service from runlevel
+- **post_deinstall**: Cleans up empty directories
+
+### Installation Test
+
+```bash
+# Install the package
+sudo apk add --allow-unstable ./releases/linux-patch-api-*.apk
+
+# Verify installation
+rc-service linux-patch-api status
+linux-patch-api --version
+
+# Check installed files
+apk info -L linux-patch-api
+
+# Verify config files exist
+ls -la /etc/linux_patch_api/
+
+# Remove package
+sudo apk del linux-patch-api
+```
+
+**Important:** Alpine uses **OpenRC** instead of systemd. Key differences:
+- Start service: `rc-service linux-patch-api start`
+- Stop service: `rc-service linux-patch-api stop`
+- Check status: `rc-service linux-patch-api status`
+- Service init script: `/etc/init.d/linux-patch-api`
+- The `abuild` tool generates signing keys automatically for CI builds

+
+**Prerequisites:** `systemd` (included by default on Arch)
+
+**Post-install:** The package automatically creates directories, copies example configs, enables the service, and prints next steps. Configure `/etc/linux_patch_api/config.yaml` and place TLS certificates in `/etc/linux_patch_api/certs/` before starting.
+
+**Note:** Arch uses systemd by default. The install hook runs `systemctl enable` but does not start the service. You must configure before starting.
+
+#### Alpine Linux (.apk)
+
+```bash
+# Install the package
+sudo apk add --allow-unstable ./linux-patch-api-1.0.0-r0.apk
+
+# Verify installation

+```
+
+**Prerequisites:** `openrc` (included by default on Alpine)
+
+**Post-install:** The package automatically creates directories, copies example configs, adds the service to the default runlevel, and prints next steps. Configure `/etc/linux_patch_api/config.yaml` and place TLS certificates in `/etc/linux_patch_api/certs/` before starting.
+
+**Important differences from systemd-based systems:**
+- Alpine uses **OpenRC** instead of systemd. Use `rc-service` commands instead of `systemctl`
+- Start service: `rc-service linux-patch-api start`
+- Stop service: `rc-service linux-patch-api stop`
+- Check status: `rc-service linux-patch-api status`
+- The service is added to the `default` runlevel automatically on install
+- Service init script: `/etc/init.d/linux-patch-api`
+
 ### Manual Installation
 
 For systems without package manager support:
 
 ```bash
 # Run interactive installer (requires root)
-./install.sh
+sudo ./install.sh
 ```
 
 The installer will:
 - Detect operating system
-- Create system user and group
-- Set up directory structure
-- Install binary and configuration files
+- Create directory structure (`/etc/linux_patch_api/`, `/var/lib/linux_patch_api/`, `/var/log/linux_patch_api/`)
+- Install binary to `/usr/bin/linux-patch-api`
+- Install example configs
 - Configure systemd service
+- Set correct permissions
 
 ### Building from Source
 
+#### Prerequisites (all platforms)
+
+- Rust toolchain (stable channel, 1.75+)
+- OpenSSL development headers
+- systemd development headers
+- C compiler (gcc)
+
+#### Build Debian Package (.deb)
+
 ```bash
-# Clone repository
-git clone https://gitea.internal/linux-patch-api.git
-cd linux-patch-api
-
-# Build release binary
-cargo build --release --target x86_64-unknown-linux-gnu
-
-# Build Debian package
-dpkg-buildpackage -us -uc -b
-
-# Or build RPM package
-rpmbuild -ba linux-patch-api.spec
+# On Debian/Ubuntu
+apt-get install -y build-essential debhelper pkg-config libsystemd-dev libssl-dev cargo rustc
+cargo build --release
+sudo dpkg-buildpackage -us -uc -b
 ```
 
+#### Build RPM Package (.rpm)
+
+```bash
+# On Fedora/RHEL/CentOS
+dnf install -y rpm-build cargo rust gcc openssl-devel systemd-devel pkgconfig
+cargo build --release --target x86_64-unknown-linux-gnu
+chmod +x build-rpm.sh
+./build-rpm.sh
+```
+
+**Note:** The RPM spec includes `BuildRequires` for native RPM build environments. When building in CI containers (where deps are pre-installed via apt-get), these are informational only.
+
+#### Build Arch Package (.pkg.tar.zst)
+
+```bash
+# On Arch Linux/Manjaro
+pacman -Syu --noconfirm rust cargo systemd git base-devel gcc
+cargo build --release
+chmod +x build-arch.sh
+SKIP_CARGO_BUILD=1 ./build-arch.sh
+```
+
+**Note:** The build script creates a `builduser` for `makepkg` when running as root (typical in CI). The `.install` hook handles directory creation, config copying, and service enablement.
+
+#### Build Alpine Package (.apk)
+
+```bash
+# On Alpine Linux 3.18+
+apk add --no-cache alpine-sdk rust cargo openssl openssl-dev elogind-dev musl-dev abuild gcc
+cargo build --release --target x86_64-unknown-linux-musl
+chmod +x build-alpine.sh
+SKIP_CARGO_BUILD=1 ./build-alpine.sh
+```
+
+**Important:** Alpine requires the `x86_64-unknown-linux-musl` target for static linking. The build script handles `abuild` key generation and runs as a `builduser` when executed as root.
+

+# Fix Non-Ubuntu Package Builds
+
+## Goal
+All platform packages must produce identical install results as the Debian/Ubuntu package.
+
+## Debian Baseline Behavior
+- No system user creation (service runs as root)
+- Directory ownership: root:root
+- Create dirs: /etc/linux_patch_api/certs, /var/lib/linux_patch_api, /var/log/linux_patch_api
+- Permissions: 750 on config dirs, 755 on data/log dirs
+- Copy .example configs to live configs if not present
+- Enable service (systemd or rc-update)
+- Print next-steps message
+
+## Tasks
+- [x] 1. Fix Arch linux-patch-api.install - removed system user creation, root:root ownership, matches Debian
+- [x] 2. Fix Arch build-arch.sh - fixed $startdir path, added source=() array
+- [x] 3. Fix RPM linux-patch-api.spec - uncommented BuildRequires, added runtime deps, removed system user, root:root ownership
+- [x] 4. Fix Alpine linux-patch-api.apk-install - removed system user creation, root:root ownership, matches Debian
+- [x] 5. Fix Alpine build-alpine.sh - co-located install script with APKBUILD, used install -Dm commands
+- [ ] 6. Verify all platforms produce consistent results (needs CI run)
+
+## Changes Summary
+
+### Arch Linux
+- **configs/linux-patch-api.install**: Removed user/group creation, changed ownership to root:root, matches Debian preinst/postinst
+- **build-arch.sh**: Fixed PKGBUILD package() to use $startdir (not $srcdir), added source=() array
+
+### RPM (Fedora/RHEL/CentOS)
+- **linux-patch-api.spec**: Uncommented BuildRequires (cargo, rust, gcc, openssl-devel, systemd-devel, pkgconfig(systemd)), added runtime Requires (openssl-libs, ca-certificates), removed system user creation from %pre, changed ownership to root:root in %pre, matches Debian behavior in %post
+
+### Alpine Linux
+- **configs/linux-patch-api.apk-install**: Removed addgroup/adduser, changed ownership to root:root, matches Debian preinst/postinst
+- **build-alpine.sh**: Restructured to co-locate install script with APKBUILD in workspace directory, used install -Dm commands in package() function, fixed $startdir references
