When a primary process initializes, the location of the config file is important. The default is /var/run/.rte_config

To run multiple primary processes, the --file-prefix= option is used to specific a custom location for the config file. Eg: --file-prefix=testing    /var/run/.testing_config

The rte_eal_check_primary_alive(const char*) function takes a char* parameter - this is the location of the config file that the secondary process will wait for. Setting it to the correct value will make this secondary process wait for the corresponding primary process.
