updatercd

Updatercd is a daemon designed to coordinate and automate software updates on Unix-like systems. It integrates with the host distribution’s package management subsystem to check for available updates, download them, and apply installations according to defined policies. The goal is to provide a centralized, automated update workflow that minimizes manual intervention while maintaining system stability.

Typical functionality includes regular update checks and repository monitoring, scheduling of installations within configurable time windows, and enforcement of update policies such as automatic security updates or manual approval for certain package groups. Updatercd often supports transactional updates through the underlying package manager, offers logging and auditing of update events, and can provide dry-run or preview modes to show what would be updated without performing changes. It may also include mechanisms for rollback or system snapshots if the platform supports them, and user-facing notifications to inform about available or completed updates.

Architecturally, updatercd is usually a background service composed of a core daemon, adapters or backends for common package managers (such as APT, DNF, Pacman, or others), and a policy or rules engine that defines how and when updates should be applied. It can expose interfaces for front-ends (command-line tools, graphical interfaces, or inter-process communication) and tends to store configuration in dedicated files or directories under /etc.

Configuration typically covers update frequency, allowed update types, reboot behavior after updates, notification preferences, and any exceptions or maintenance windows. The exact implementation and feature set of updatercd can vary by distribution or project, and some systems may provide alternative update orchestration tools with similar goals.
