Upgrade Flake Inputs

Update flake.lock to pull in the latest commits from all flake inputs. This gets you newer package versions without changing NixOS release channels.

What this does

• Updates all inputs to their latest commits (nixpkgs, home-manager, etc.)
• Does NOT change release channels (stays on same NixOS version)
• Safe operation - can always rollback

Process

1. Update the lock file

``bash just update ` This runs nix flake update and updates flake.lock`.

1. Build and verify (safe dry-run)

``bash just check `` Builds all configurations without applying. If this fails, fix errors before proceeding.

1. Apply the update (when ready)

``bash just switch ``

1. Verify services are running

``bash systemctl status docker tailscaled ``

Rollback if needed

When you're done echo out the instructions to:

# Revert to previous system generation
sudo nixos-rebuild switch --rollback

# Revert flake.lock to previous state
git checkout flake.lock

Tips

• show the user what ch git diff flake.lock to see what changed before applying
• Old boot entries remain available for rollback until garbage collected
