title: linux separate user profiles on the same home dir
body: <p>I have <strong>appuser01</strong> and <strong>appuser02</strong> accounts and home dir <strong>/appuser01</strong> as homedir for user appuser01.
  I'd like to have the same homedir <strong>/appuser01</strong> for user <strong>appuser02</strong> as well, but user <strong>appuser02</strong> should use different profile file. 
  The intention is to have different env variables for different users but in the same folder. Please let me know the best option to handle this. </p>
