This was pointed to by the "custom" cc3go that Bob had apparently built, which after running "startup -P", it ran "/d0/sys/config.os9" which set the system paths.

For this you would need to modify the shell to read commands from a
file when it starts, before reading from the console. And not just run
a startup file in a new shell like it does now.
