I think btrfs probably is meant to provide a lot of the modern |
| 28 |
features like reiser4 or xfs (tail-packing, indexing, compression, |
| 29 |
snapshots, subvolumes, etc). Don't know if it is considered stable |
| 30 |
enough for your usage but at least it is under active development and |
| 31 |
funded by large names. I think if you would consider reiser4 as a |
| 32 |
possibility then you should consider btrfs as well. |
