I wonder how Fedora started using btrfs as the default for their desktop version when RedHat had deprecated it years ago. Never used btrfs but I see corruption reports in here everytime I read about it, and it's been in development for over a decade and this thing needs to be put to rest before it eats more people's data. Hopefully bcachefs becomes feature parity and stability against zfs to provide a modern filesystem to wider Linux audience at last. Funny to see we're still using ext4 as the default filesystem which is nothing fancy forever.

> I wonder how Fedora started using btrfs as the default for their desktop version when RedHat had deprecated it years ago. Because the Fedora community wanted to, basically. They're not obligated to go along with whatever Red Hat wants to do, although there is naturally some alignment there. Plus having a different default filesystem really isn't that big of a deal. disclosure: I work for Red Hat.

  Well, I always hear about data loss incidents whenever btrfs shows up in HN comments, so I thought making it a default in Fedora desktop sounded like a big deal as there must've been a good reason on why RH dropped it.

    I know nothing about the reasons it was dropped (apart from what I've read on HN, ironically) but keep in mind this was years ago, when it was still deeply, deeply troubled and there was a lot of churn going on. "Churn" and "stable" kernels like RHEL don't mix well.

    Maybe it's always the same stories. I haven't read of any happening in the past couple years. Of the two I've read in this thread, one happened ages ago, the other involves raid5 which AFAIK is not recommended for production use. Also, kernel bugs tend to get fixed, especially now that btrfs is recommended by a few distros.
