Currently src/mongo/db/modules/enterprise/jstests/audit/log_rotate_startup.js consistently fails on Enterprise RHEL 8.1 PPC64LE and **Enterprise macOS , because the javascript test runners use GMT-5 (local timezone) on these variants when generating test file names for causing collisions with rotating audit log files, instead of the GMT-0 used by all other tested variants.
The test consistently fails because mongod uses GMT-0 when it rotates files, thus for these two variants, there is never a collision, the server starts normally and the test fails.
To correct this failing test and prevent further false-negatives we can use failpoints to test audit log rotation failing at various points in the process instead of relying on the variable external environment.
