51_install_sysupdate_function.yml - Usage Guide

Modifies State Reversible

Purpose

Installs the sysupdate function into the target user’s shell. In an interactive session the function runs apt + snap + flatpak maintenance and light cleanup. Shared model: 43_install_kubectl_aliases.

This playbook does not run maintenance; it only places the function. To apply the same maintenance remotely with Ansible, use 52_run_sysupdate. For package updates on Kubernetes nodes with drain/reboot, use 41_patch_and_reboot_nodes.

How to run 

ansible-playbook -i inventories/musteri_a/hosts.ini playbooks/51_install_sysupdate_function.yml
ansible-playbook -i inventories/musteri_a/hosts.ini playbooks/51_install_sysupdate_function.yml \
  --extra-vars 'shell_aliases_state=absent'

After install, on the target host:

source ~/.bashrc   # bash login shell; use ~/.zshrc or ~/.profile if that is the login shell
sysupdate

What the function does

  1. Disk usage (before)
  2. apt update / upgrade -y / autoremove / autoclean
  3. If snap is present: snap refresh and cleanup of disabled revisions
  4. If Flatpak is present: flatpak update and unused removal
  5. Thumbnail cache older than 30 days
  6. Trash count (does not empty it)
  7. Duration, disk (after), /var/run/reboot-required warning

The function asks for sudo. It does not reboot.
