Subject: [ANN] Ubuntu PPA for bcache-tools and blocks

Hello,
I've published various bcache-related packages to

https://launchpad.net/~g2p/+archive/storage/

The packages are built for saucy and raring, and can be
added with

sudo add-apt-repository ppa:g2p/storage
sudo apt-get update
sudo apt-get install bcache-tools blocks

bcache is a hybrid caching layer that speeds up HDDs
with SSDs; it was merged in Linux 3.10. Backported
Ubuntu kernels are available at

http://kernel.ubuntu.com/~kernel-ppa/mainline/

bcache-tools contains udev and initramfs integration and
some command-line tools.

blocks is a conversion tool that can convert block devices
to bcache and lvm. Usage is described here:

https://github.com/g2p/blocks#bcache-conversion

This release of blocks adds a maintboot mode that can
convert root filesystems to bcache without a live cd.

A backported dkms module isn't feasible, bcache comes with work
on the block layer. Raring users should the kernels I've linked:

Latest is this one
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/
And there's a bit of docs here:
https://wiki.ubuntu.com/Kernel/MainlineBuilds

Other options for raring users: upgrade to saucy

Or build your own kernel
