“Basically, LabVIEW RT Runtime-specific changes should go in the lvrt.conf file [..]. System-wide changes should go in the ni-rt.ini file. Note, however, the vast majority of tokens that are defined for this use-case are accessible through MAX or there's little reason to change them, so except for certain circumstances, you shouldn't be editing this file.”

(Source)

The lvrt.conf file is located at /etc/natinst/share/lvrt.conf.

The ni-rt-ini file is located at /etc/natinst/share/ni-rt.ini.

See below for examples of configuration files.

Add the RTTarget.StartupVIs token under the [lvrt] section of the lvrt.conf file. If it has not been previously set, the token may not appear in the configuration file.

  RTTarget.LaunchAppAtBoot=True

These other tokens may or may not be necessary:

  server.tcp.access="+*"
  RTTarget.ApplicationPath=/home/lvuser/natinst/bin/startup.rtexe
  RTTarget.VIPath=/home/lvuser/natinst/bin
  RTTarget.EnableFileSharing=True
  server.tcp.serviceName="Main Application Instance/VI Server"
  xwmShellRect.Title=3x3+3+29
