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

   bashCopy

   just update
   

   This runs nix flake update and updates flake.lock.

2. Build and verify (safe dry-run)

   bashCopy

   just check
   

   Builds all configurations without applying. If this fails, fix errors before proceeding.

3. Apply the update (when ready)

   bashCopy

   just switch
   

4. Verify services are running

   bashCopy

   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
