Comment (by pierre):

 I think we should recommend to use `sudo -E -H` instead of just `sudo -E`
 in the note for sudo configuration. But we might be concerned about
 creating files in /root directory...

 The code creating this directory seems to be in
 .bundle/gems/rdoc-7.0.3/lib/rdoc.rb:
 {{{
 [...]
 ##
   # Searches and returns the directory for settings.
   #
   # 1. <tt>$HOME/.rdoc</tt> directory, if it exists.
   # 2. The +rdoc+ directory under the path specified by the
   #    +XDG_DATA_HOME+ environment variable, if it is set.
   # 3. <tt>$HOME/.local/share/rdoc</tt> directory.
   #
   # Other than the home directory, the containing directory will be
   # created automatically.

   def self.home
     rdoc_dir = begin
                 File.expand_path('~/.rdoc')
               rescue ArgumentError
               end

     if File.directory?(rdoc_dir)
       rdoc_dir
     else
       require 'fileutils'
       begin
         # XDG
         xdg_data_home = ENV["XDG_DATA_HOME"] ||
 File.join(File.expand_path("~"), '.local', 'share')
         unless File.exist?(xdg_data_home)
           FileUtils.mkdir_p xdg_data_home
         end
         File.join xdg_data_home, "rdoc"
       rescue Errno::EACCES
       end
     end
   end
 [...]
 }}}
 (I'm not a ruby expert but the code seems to create ~/.local/share if it
 does not exist)

 We may want to use:
 {{{
 XDG_DATA_HOME=/tmp make install
 }}}
 (with a command explanation of course)
