This situation can result in some harmless STDERR going to your web server’s error log as errors.

If you experience this your options are:

1. Ignore the log entries
  2. Create the directory “$home” if it is safe to do so.
  3. Change the `nobody` user’s home directory to one that exists. e.g. `usermod --home / nobody`
$sep
END_HOMEDIR
