title: Ruby where is etc module file and can it be customized?
body: <p>Etc module is great, but if I used NIS or LDAP where passwd, group, and shadow are not from /etc/{passwd, group, shadow}, then Etc module is not going to help.</p>
  
  <p>Is it possible to edit the Etc module path's /etc/{passwd,group,shadow}? </p>
  
  <p>On my Linux box, I have gone into /usr/lib/ruby/1.8, there are modules but couldn't fine etc.rb or related modules.  </p>
  
  <p>Many thanks</p>
