This is true on Linux and Windows, but misses an edge case on BSDs (including Apple). As seen below, it actually \"replaces trailing X's with random characters and then appends six additional random characters to the prefix to create a unique directory name\".\r\n```\r\n// on macOS\r\n\u003e fs.mkdtempSync(path.join(os.tmpdir(), 'foox')) // does as documented\r\n'/tmp/fooxz5Ve7r'\r\n\r\n\u003e fs.mkdtempSync(path.join(os.tmpdir(), 'fooX')) // also replaces the X from the prefix\r\n'/tmp/foo1PqEasA'\r\n         ^-- not an 'X'\r\n```\r\n\r\nI think this is just a doc issue, but opening this as an issue to hear what others think.","author":{"url":"https://github.com/vtjnash","@type":"Person","name":"vtjnash"},"datePublished":"2019-03-04T17:28:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/26435/node/issues/26435"}
