Fix RUN_AS_USER feature for UNIX environments (linux, solaris,macos)
--------------------------------------------------------------------

         Key: CONTINUUM-554
         URL: http://jira.codehaus.org/browse/CONTINUUM-554
     Project: Continuum
        Type: Bug

  Components: Core system  
    Versions: 1.0.2    
 Environment: any unix like OS running continuum as non root user.
    Reporter: Rainer.Pruy
 Attachments: DIFF

When RUN_AS_USER is specified in the run.sh script continuum will not start.

This  is caused by a change in the current directory resulting from calling "su - .....".
In the regular (non RUN_AS_USER) case, the current directory is changed to the os specific calling directory "bin/<OS>/".
After calling "su - ..." the current directory is the home directory of the target user.

For fixing the following two possibilities come to mind:

1: change to the correct directory within the command passed to "su"
    (See the enclosed patch for bin/linux/run.sh" a similar patch may be applied for solaris and macos)

2. avoid using "su - "
     Calling "su" without "-" option will preserve the current environment and not change the current directory.

I personally prefer method '1'. Usually the run user will be a dedicated user for running continuum. Using "-" option will establish a default  environment for this user. Theat is easy to be controlled and configured and avoids conflicts with other applications.
