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
   1just update

   This runs nix flake update and updates flake.lock.

2. Build and verify (safe dry-run)

   bash
   1just check

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

3. Apply the update (when ready)

   bash
   1just switch

4. Verify services are running

   bash
   1systemctl status docker tailscaled

Rollback if needed

When you're done echo out the instructions to:

bash
1# Revert to previous system generation
2sudo nixos-rebuild switch --rollback
3
4# Revert flake.lock to previous state
5git 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
