    "Tumbleweed's transactional updates require Btrfs be present on the file-system, due to its snapshotting support."

    And there lies the rub, shorter SSD buying cycles.

      Well, it's not enabled by default, so shorter buying cycles are opt-in at the moment.
      Though seriously, it will create a copy of stuff you're updating and delete it afterwards or restore it, depending on the update outcome. Worst case scenario, this writes all the files you're updating twice; less if (parts of) files are identical. And you get a working, atomic update in return. I can hardly think or a more useful way to add a little writing to my SSD.

        "Tumbleweed's transactional updates require Btrfs be present on the file-system" .. yeah right. What a great OS.. to bad it's tying itself to a sinking turd.

          Are you 100% positive this is forever tied to btrfs and btrfs isn't just the launch vehicle, with more file systems to come?

            I somehow suspect that it's unlikely you will notice that. even btrfs does not write multiple GBs per day of metadata, and modern SSDs will last decades with a few GBs of writes per day.

              For other filesystems to qualify they would be CoW, as the "atomic snapshotting" can only happen if the filesystem itself is CoW (so it can do atomic snapshots itself). So afaik the only possible replacement in an unknown future is XFS (that is aiming at that now).

              I would question his idea of sinking turd instead.

                So which filesystem that supports atomic, CoW snapshotting and is supported by the Linux kernel would you recommend they use?
