For the past couple of years, I've been doing btrfs snapshots of my root |
| 19 |
filesystem for all big updates, and it works very well for me. |

In order to go along with the Gentoo's "we're about choice" spirit, you |
| 22 |
could create a plugin framework that supports multiple backends for |
| 23 |
performing snapshots and doing bootloader configuration. That way, you |
| 24 |
could make it work with whatever the user's choice of |
| 25 |
filesystem/bootloader combination happens to be. |
