pushed out in the last week as part of stable release version 38 of chromeOS? There are hundreds of thousands of tickets, end users won't follow those, they care once stuff lands on their systems.

As the OP of the /r/linux thread... What inspired the thread is that I bought an SD card and while on the dev build of chromeOS I was unable to use it with ext4. I distinctly remembered it being listed as supported at one point a year or so ago and then I ran upon this thread: http://www.reddit.com/r/chromeos/comments/2iuix3/trying_to_i...

So I made a thread on /r/linux and it absolutely exploded. I made it figuring that a number of users would click through and post that this was a stupid change and hopefully get the decision reverted. They claimed there was no userbase for such a feature and I knew exactly where to find one. That said, it blew up way more than I was expecting.
