title: Linux default file permissions
body: <p>I'm pretty much breaking my head over this one.
  I'm running an exact ams Debian system as several other I am managing with the same kernel and same setup, however, the files being created by my java process running as a private user aren't getting the execute permission for the owner by default, which breaks the process.</p>
  
  <p>The umask is 0022, so that's correct, I've tried setting up ACL's, but those seem to be getting ignored. The setup of the users itself also completely matches the setup on other machines where it does work.
  It starts the java process trough sudo for the specific user. 
  I'm pretty much at the end of what I can think of.</p>
