How to install carefully

• Browse the package with

  % pacman -l BU:Python
  

• Fetch the package before installing it with

  % pacman -fetch BU:Python
  

• Examine all the shell commands that might be executed with

  % pacman -domain -dom all | grep shell
  

• You can extract and examine the Pacman source codes before installation with

  % pacman -extract-sources .
  

• You can extract and examine all of the downloads before installation with

  % pacman -extract-downloads .
  

• Step through the installation stopping at every shell command with

  % pacman -install -ask shell
  

  or with % pacman -install -ask action to stop at each Pacman action.
