tl;dr XFS will support using filesystem images as if they were directories, kind of like an "internal loop", which will allow (with the help of copy-on-write data, which they support in recent versions) having subvolumes/snapshots.
- josteink 9y agoIt might just be how you present it, but to me that sounds like using multiple layers of hacks to implement use-cases other filesystems were carefully designed to support in the first place, and that sounds extremely unreliable and brittle. I'll stick to ZFS :)
- diegocg 9y agoYeah, these subvolumes are going to have scalability issues compared with cleanly designed subvolumes such as in ZFS. But I wouldn't describe them as a hack - it's a rather interesting feature that not other filesystem has explored before. I would describe it as "loop devices done well". I don't think reliability will be a problem, for the upper layer these embedded filesystems are in fact just files.
