Phoronix has an article up about some interesting ideas of Lennart Poettering about what could be a possible future for Linux:
Lennart Poettering of systemd and PulseAudio fame has published a lengthy blog post that shares his vision for how he wishes to change how Linux software systems are put together to address a wide variety of issues. The Btrfs file-system and systemd play big roles with his new vision. Long story short, Lennart is trying to tackle how Linux distributions and software systems themselves are assembled to improve security, deal with the challenges of upstream software vendors integrating into many different distributions, and "the classic Linux distribution scheme is frequently not what end users want."

Right with you on this.
I hope to use Btrfs and its snapshots, checksums and all.
Reading LP's projects to use hundreds of subvolumes means it will be such a mess that I won't know what I am using, which subvolumes I need to backup...
And he says ext4 will be supported... by putting btrfs filesystems in a loop file !
Please keep this on ONE distribution if this feature-set is right for you but do not push this everywhere...
