debian-knowledge-patch

What problem does it solve?

This skill collects and summarizes Debian 13 (Trixie) changes that are missing from older model knowledge and that can cause failed upgrades, broken services, or unexpected system behavior so administrators can plan and remediate before rebooting or deploying.

Core Features & Use Cases

• Breaking-change reference: highlights high-impact changes such as /tmp becoming tmpfs, systemd run0, OpenSSH DSA removal, login tracking replacements, and dm-crypt default changes.
• Upgrade preparation guidance: lists pre-upgrade checks, package-specific precautions (MariaDB, RabbitMQ, PostgreSQL), and required package installs like systemd-cryptsetup to avoid bricking encrypted systems.
• Architecture and sizing notes: documents arch-specific constraints (i386 legacy-only, riscv64 support, armel final release) and /boot sizing requirements to prevent upgrade failures.
• Use Case: generate a per-host upgrade checklist for Bookworm-to-Trixie migrations, audit servers for incompatible defaults, and produce remediation steps for services and encryption settings.

Quick Start

Load the debian-knowledge-patch and ask for a Bookworm-to-Trixie upgrade checklist focused on systemd, OpenSSH, tmpfs /tmp, dm-crypt, and database migrations.
