Review comment:
I was looking into this in our environment and was able to get the below
piece of code working:
` if (dirToCreate.mkdirs() && dirToCreate.exists()) {
Files.setPosixFilePermissions(dirToCreate.toPath,
PosixFilePermissions.fromString("rwxrwx---"))
created = dirToCreate
}`
@Kimahriman do you mind testing this piece of code in your environment? It
seems like the code referenced in the TODO does not pass the unit tests and
also does not work in our environment.
If this looks good we can clean it up.
