About Third-Party Applications
The RPMs for the Third-Party Applications are available in the repository at https://devhub.cisco.com/artifactory/open-nxos/9.2.1/. These applications are installed in the native host by using the dnf command in the Bash shell or through the NX-OS CLI.
When you enter the dnf install rpm command, a Cisco DNF plug-in gets executed. This plug-in copies the RPM to a hidden location. On switch reload, the system reinstalls the RPM.
For configurations in /etc, a Linux process, incrond , monitors artifacts that are created in the directory and copies them to a hidden location, which gets copied back to /etc.
