A friend of mine shared this with me yesterday. PC World even picked up on the story.
If you’re a Steam fan running Linux, the last thing you’ll want to do in the next few days is mess with your Steam files. Users on Valve’s GitHub Steam for Linux page are complaining about a nasty bug that has the potential to wipe out every single personal file on your PC. Even worse, users say the bug will even wipe out documents on USB connected drives. So much for local backups.
That’s a pretty serious bug. I hope Valve gets on that ASAP.
