I tried running mongo-orchestration's test suite, and in the process of that mongod died with an error message while not writing anything to its log file. The error output was sent to standard output stream, whereas I expected to find error output in the standard error stream.

This is the config I used, saved as /tmp/c:

nojournal=true
configsvr=true
dbpath=/tmp/mongo-A_fAH5
logpath=/tmp/mongo-A_fAH5/mongod.log

speed% /usr/local/m/versions/4.1/mongod --config /tmp/c --port 1027            
2019-06-10T20:44:21.454-0400 F  CONTROL  [main] Failed global initialization: BadValue: nojournal is not allowed when configsvr is specified

At the end of this execution, /tmp/mongo-A_fAH5/mongod.log did not exist and the error message was printed to stdout.

Checked on master (4.3.0).
