Launching puppet via bundle exec with a different encoding / testing scrubbing

  • modify bin/puppet wrapper

    • change #!/usr/bin/env ruby to #!/usr/bin/env ruby -E ISO-8859-1

  • To test the Etc provider on OSX

    • change lib/puppet/provider/user/directoryservice.rb, commenting the line defaultfor :operatingsystem => :darwin
    • change lib/puppet/provider/user/useradd.rb, commenting the line commands :add => "useradd", :delete => "userdel", :modify => "usermod", :password => "chage"

  • To perform some checks, mod lib/puppet/util/character_encoding.rb like:

Determine Windows codepage -> Ruby Encoding map

This chart has things broken down by Rubys response after calling chcp locally.

  • Invalid codepage means trying to change active codepage on English Windows 2008R2 is broken
  • Ruby failure indicates the inability of Ruby to even load given a codepage (though it did still properly identify the Ruby Encoding)
  • In most cases, Ruby considers the codepage ASCII-8BIT / BINARY
Name Value
710 Invalid codepage
12001 Invalid codepage

brew uninstall --force docker
brew uninstall --force docker-machine
brew unlink docker

Update partitions of existing LibreElect install

ssh root@libreelecip
pw: libreelec
