dotfiles-testing

This is a repository created to aid the testing of my dotfiles without potentially trashing my own system. This repository consists of notes and Packer configuration to be able to have a VM ready to run ./install.sh on.

This repository uses VirtualBox and isn't designed for continuous integration, as dotfiles will generally both require passwords to be entered in and need visual verifying that graphical changes are correct.

Making an Ubuntu VM

Create the VM

  1. Download the ISO
  2. Make a VM
  3. Start the VM with the ISO

Post-install changes

  • sudo apt install -y openssh-server virtualbox-guest-dkms virtualbox-guest-x11

Making a macOS (Catalina) VM

Build the ISO

  1. Download Install Catalina from app store - once it has downloaded and started, it will be saved at /Applications/Install macOS Catalina.app
  2. Run the following commands:
hdiutil create -o /tmp/Catalina -size 8500m -volname Catalina -layout SPUD -fs HFS+J
hdiutil attach /tmp/Catalina.dmg -noverify -mountpoint /Volumes/Catalina
sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Catalina --nointeraction
hdiutil detach /volumes/Install\ macOS\ Catalina
hdiutil convert /tmp/Catalina.dmg -format UDTO -o ~/Desktop/Catalina.cdr
mv ~/Desktop/Catalina.cdr ~/Desktop/Catalina.iso

Create the VM

Create a new VirtualBox vm with the following configuration:

  • At least 25 GB of disk space
  • Decent slug of RAM
  • multiple processors
  • No floppy (system tab)
  • PIIX3 chipset (system tab)
  • 12 8MB of video memory

Run the following commands:

VBoxManage modifyvm "Your VM Name" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3"
VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple"
VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1
VBoxManage setextradata "Your VM Name" VBoxInternal2/EfiGraphicsResolution 1920x1080

Install the VM

  1. Start the VM with the ISO
  2. Use the Disk Utility app in the VM to erase the VBOX HARDDISK Media - call it macOS Catalina
  3. Close Disk Utility
  4. Run installer

Post-install changes

  • Enable ssh server
