The core challenge is generating valid systemd unit file syntax programmatically and installing them to appropriate paths while maintaining testability without root privileges. + +Systemd timers consist of two linked files: a `.timer` file that defines the schedule and a `.service` file that defines the action. For periodic tasks like sysext updates, we need: +1. A timer that triggers on a calendar schedule (e.g., daily) +2. A service that runs `updex update` (or similar) +3. Both files installed to `/etc/systemd/system/` (or user-configurable path) + +The existing `go-systemd` library from CoreOS provides a well-tested `unit` package for serializing unit files. However, given the project's pattern of minimal dependencies and the simplicity of unit file format (INI-like sections), hand-rolling generation is equally viable. The project already uses `gopkg.in/ini.v1` for parsing `.transfer` files, but unit file generation is straightforward enough that templates or simple string builders work well. + +**Primary recommendation:** Create a new `internal/systemd` package with types for timer/service configuration and simple template-based generation, using configurable paths for testability. + +## Standard Stack + +The established libraries/tools for this domain: + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| Go stdlib `text/template` | Go stdlib | Generate unit file content | Built-in, familiar, handles escaping | +| Go stdlib `os` | Go stdlib | File operations | Standard for file I/O | +| Go stdlib `os/exec` | Go stdlib | Run `systemctl` commands | Standard for command execution | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| `path/filepath` | Go stdlib | Cross-platform path handling | Path construction | +| `fmt` | Go stdlib | String formatting | Simple unit file generation alternative | + +### Alternatives Considered +| Instead of | Could Use | Tradeoff | +|------------|-----------|----------| +| `text/template` | `github.com/coreos/go-systemd/v22/unit` | More robust but adds dependency;
