"MeeGo, the mobile Linux operating system that came about when
Intel and Nokia joined forces to marry Moblin and Maemo, will be
using Btrfs as its default file-system.
"A very early MeeGo development release has been available for a
few weeks and there is also an Intel App Store in development. The
latest news for MeeGo is that it's using Btrfs as its default
file-system, as confirmed on the mailing list.
"MeeGo is now the first high-profile Linux distribution that
will be deploying Btrfs by default. Btrfs has been in the mainline
Linux kernel since the Linux 2.6.29 release and has been an
Anaconda installation option within Fedora for a few releases."
