NetWorker: Installation of third-party software on NVE appliance

Does the NetWorker Virtual Edition (NVE) appliance support installation of third-party utilities on the NVE operating system?

There is a request in an environment to install a third-party utility to perform some operation on the NVE, for example: password/user management, file system management, anti-virus, so on

NetWorker engineering has confirmed that modifying the configuration of or adding extra software to NVE is not supported since the potential consequences are unknown. 

NVEs differ from standard Linux server deployments in that:

• The NVE appliance is provided as an "as-is" solution and includes the essential components necessary to perform its intended function.
• Dell provides operating system updates through OsRollup-YYYY-R#-V# packages. These are applied through a provided installation utility (avinstaller).
• NetWorker package upgrades are provided through .avp packages and applied through a provided installation utility (avinstaller).

System rollups and NetWorker upgrades have strict operational expectations. Any unexpected changes to the NVE can cause them to malfunction or fail. Changes to the NVE which cause update failures require an NVE redeployment with a default configuration and NetWorker Disaster Recovery (nsrdr).
