<no title> — PMIx Reference Run Time Environment 3.0.2a1 documentation

Allow execution as root (STRONGLY DISCOURAGED).

Running as root exposes the user to potentially catastrophic file system corruption and damage — e.g., if the user accidentally points the root of the session directory to a system required point, this directory and all underlying elements will be deleted upon job completion, thereby rendering the system inoperable.

It is recognized that some environments (e.g., containers) may require operation as root, and that the user accepts the risks in those scenarios. Accordingly, one can override PRRTE’s run-as-root protection by providing one of the following:

- The `--allow-run-as-root` command line directive

- Adding BOTH of the following environmental parameters:

  > - `PRTE_ALLOW_RUN_AS_ROOT=1`

  > - `PRTE_ALLOW_RUN_AS_ROOT_CONFIRM=1`

Again, we recommend this only be done if absolutely necessary.
