Prerequisites

• [x] Write a descriptive title.
• [x] Make sure you are able to repro it on the latest version
• [x] Search the existing issues.

Summary

./dsc will hang forever awaiting sudo password input for commands. sudo ./dsh causes homebrew to fail because homebrew doesn't want to be run as root.

Steps to reproduce

$schema: https://raw.githubusercontent.com/PowerShell/DSC/refs/heads/main/schemas/v3/config/document.json
resources:
  - name: Install VSCode
    type: DSC.PackageManagement/Brew
    properties:
      packageName: visual-studio-code

  - name: Install Neovim
    type: DSC.PackageManagement/Brew
    properties:
      packageName: neovim

  - name: Install PowerShell
    type: DSC.PackageManagement/Brew
    properties:
      packageName: powershell/tap/powershell

  - name: Add PowerShell to etc shells
    type: Microsoft.DSC.Transitional/RunCommandOnSet
    properties:
      executable: /bin/zsh
      arguments:
        - -c
        - 'PWSH_PATH=$(which pwsh); if ! grep -q "$PWSH_PATH" /etc/shells; then echo "$PWSH_PATH" | sudo tee -a /etc/shells; fi'

  - name: Change Default Shell
    type: Microsoft.DSC.Transitional/RunCommandOnSet
    properties:
      executable: /bin/zsh
      arguments:
        - -c
        - 'PWSH_PATH=$(which pwsh); chsh -s "$PWSH_PATH" $(whoami)'

trying to su before running ./dsc doesn't work either

I think what you need is to wait for this feature: https://github.com/PowerShell/DSC/issues/666

Unless you set sudo to not prompt for a password (which is a really bad practice), you really shouldn't use sudo in a script which is what RunCommandOnSet basically does.
