Rebuild Macbook Air - Feb 2023 Long Overdue

[scottmuc]

Yay for Repaving!

As much as possible is documented inline in this issue template. In case of problems you may find help by viewing all the previous repave issues. Have fun!

Things to do with the existing build

• [x] Create USB stick with latest macOS

  Instructions

  • Format a USB (> 16GB) stick and name it UNTITLED
  • Fetch the latest version of macos from the App Store
  • Run the following

  $ sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/UNTITLED --nointeraction
  Password:
  Erasing disk: 0%... 10%... 20%... 30%... 100%
  Copying to disk: 0%... 10%... 20%... 30%... 40%... 50%... 60%... 70%... 80%... 90%... 100%
  Making disk bootable...
  Install media now available at "/Volumes/Install macOS Big Sur"

• [x] Create credentials for the rebuild

  Instructions

  Run create-repave-secrets with an argument that follows the naming convention of:

  machine.<month name>.air

• [x] Backup anything worth keeping

  Instructions

  Generally, this means look at the following directories for things that I might want to carry over to the fresh install or possibly consider saving to a cloud service:

  • Desktop
  • Documents
  • Downloads

Rebuild steps

• [x] Reboot to load installer

  Instructions

  Hold down the Option key to trigger the boot selection menu.

• [x] Use Disk Utility to wipe existing partition and make a new one (new name, new encryption key)

• [x] Install the OS

Post OS install steps

• [x] Install git, clone this repo, and run coalese_this_machine

  Instructions

  git # this will trigger the XCode installer which brings git along with it
  mkdir ~/workspace
  git clone https://github.com/scottmuc/infrastructure.git ~/workspace/infrastructure
  ~/workspace/infrastructure/homedirs/osx/coalesce_this_machine

• [x] Launch and configure 1 Password

• [x] Initialise 1 Password CLI

• [x] Map capslock to control

note to speed things up, some of the steps above can be done while coalese_this_machine is running.

Done When

• [x] Make a tiny DNS change and run terraform

  Instructions

  # Initialize and log into the 1 Password CLI
  initialize-1password
  eval $(op signin)
  # Unlock the repo in order to access values in ./secrets dir
  cd ~/workspace/infrastructure
  ./scripts/locksmith unlock
  # Initialize Terraform and apply
  cd dns
  terraform init
  ./terraform_apply

• [x] Make a signed commit mentioning this issue (exercises gpg_op)

  Instructions

  # Initialize and log into the 1 Password CLI
  initialize-1password
  eval $(op signin)
  gpg_op restore -e "scott@scottmuc.com"

• [x] Be able to push the commit (exercises ssh_op_agent)

• [x] Log into GitHub in Brave (exercises 1 Password browser extension)

• [x] Old keys and credentials are deleted (GitHub and 1Password)

• [x] Make this template slightly better

Had some issues due to asdf bootstrapping. Will commit a few changes around that. This is related to #49.

The current alacrritty-colorscheme install code installs it in the global python (which the PATH is incorrect, so I'm going to remove it). Need to install the relevant asdf plugins and then perform the installation of the tools.

There's not much to improve with this template. Despite being nearly a year since the last repave, all the steps were still important. The issues I encountered on this repave were due to the underlying automation being out of date, so some fixes need to be applied there.

Everything is running fine after the repave... calling it done.
