A deeper look into a steam-for-linux GitHub issue (https://github.com/valvesoftware/steam-for-linux/issues/3671) investigating how a steam script was able to delete the entire contents of someone's root directory. While the direct cause of the rm -rf is fairly obvious, how it was triggered in the original bug report is not, and may forever remain a mystery...
