How remarkable or interesting is this bug?

What about the handling should have been different? I note here that ext2 and ext3 are offered as file systems in Custom/Advanced partitioning and in this sense have parity with Btrfs. If this same bug occurred in ext2 or ext3 would or should that cause discussion to drop them from the installer, even if the bug were fixed within 24 hours of discovery and patch? What about vfat? That's literally the only truly required filesystem that must work, for the most commonly supported hardware so it can't be dropped, we'd just be stuck until it got fixed. That work would have to be done upstream, yes?

The concern is that in the past we haven't seen a lot engagement in the past. Maybe today that has changed as demonstrated by this thread. I'm still concerned about having this be a blocker vs. just keeping it as an option, simply because a blocker stops the entire release and it can be a last minute scramble to get things fixed. This was the ideal case for a blocker bugs and I'm skeptical about all bugs going this well. If we had a few more people who were willing to be on the btrfs alias and do the work for blocker bugs it would be a much stronger case.

Just because options are presented doesn't mean all of them are equal. ext2/ext3 and vfat have been in development for much longer than btrfs and length of development is something that's particularly important for file system stability from talking with file system developers. It's not impossible for there to be bugs in ext4 for example (we've certainly seen them before) but btrfs is only now gaining overall stability and we're still more likely to see bugs, especially with custom setups where people are likely to find edge cases.

We do need to consider that the failure case is not "I can't do X" but "my precious data which I have been trying to snapshot is now inaccessible" in a way that's even worse than say rpm database corruption. Even if it is in the advanced partitioning or not the default, we can still end up with people clicking in because they read an article about how btrfs was the hot new thing. There are two parts to this here: killing off btrfs entirely and btrfs as release criteria. I think you are correct that there's enough community support to justify keeping btrfs around at least in the kernel (I can't speak for anaconda here) As for btrfs as release criteria, I'd feel much more confident about that if we could have a file system developer on the btrfs alias. I'm glad to hear the btrfs upstream community has been receptive to bugs but it's still much easier to make things happen if we have contributors who are active in the Fedora community, especially if we want the advanced features that btrfs has (which is why people want it anyway). So, who would you suggest to work with us in Fedora?

Thanks, > So it appears you are on the btrfs alias already: fedora-kernel-btrfs: fs-maint@redhat.com,josef@toxicpanda.com,bugzilla(a)colorremedies.com This technically meets the requirements if you are willing to stay on this alias and (continue) to help with requests as needed. I would feel more confident if we had a few more people involved as well. Even better would be proactively going through the bugzillas to help find the btrfs ones.

Fedora chugs along at the rate of daily upstream Linus snapshots. If you're hitting and fixing issues before Fedora users see them, I'm curious why Fedora users would ever see them. Where does the lag come from? Are the fixes queued internally? Staged in an upstream subsystem tree? Is there a way for interested btrfs people to proactively just get those fixed in Fedora before users hit them?
