    https://github.com/apache/nifi/pull/1405
  
    I was testing this PR using Amazon Linux.
    Checking if I can refer ${NIFI_HOME} environmental value via Attribute Expression Language,
before and after applying the patch. I set run.as = 'nifi', and execute `bin/nifi.sh start`
by root user.
    
    ```properties
    # conf/bootstrap.conf
    run.as=nifi
    ```
    
    NiFi flow is simple as: `GenerateFlowFile` using dynamic attribute as `nifi.home` = `${NIFI_HOME}`,
also I added `lang` = `${LANG}` to make sure that it can refer OS env values via VariableRegistry.
    
    ## Result: Without this PR
    
    ```properties
    nifi.home=(Empty string)
    lang=en_US.UTF-8
    ```
    
    NIFI_HOME was not retrieved as expected.
    
    ## Result: With this PR
    
    ```properties
    nifi.home=/mnt
    lang=en_US.UTF-8
    ```
    
    Although NIFI_HOME was retrieved, the value was not the expected one. It should be `/mnt/nifi-1.2.0-SNAPSHOT`
but it was just `/mnt`.
    
    I also found that without `run.as` property, nifi.sh doesn't work with this PR. It seems
Command argument is not passed properly to RunNiFi:
    
    ```bash
    [root@ip-172-31-20-144 nifi-1.2.0-SNAPSHOT-root]# ./bin/nifi.sh status
    Java home: /usr/lib/jvm/jre
    NiFi home: /mnt/nifi-1.2.0-SNAPSHOT-root
    Bootstrap Config File: /mnt/nifi-1.2.0-SNAPSHOT-root/conf/bootstrap.conf
    Usage:
    java org.apache.nifi.bootstrap.RunNiFi [<-verbose>] <command> [options]
    Valid commands include: ...
    ```
    
    I will keep investigating what's going on but would like to share current status. Please
let me know if you noticed something.
    
    Thanks!

> nifi-env is a script that allows setting of certain properties external to the core run
scripts.  However, when sudo is used, the resulting subshell/child process is a separate environment
that does not have the needed information that was established in nifi-env.  This needs to
be incorporated into the run command such that those properties are preserved.
