It's really nice to see how btrfs is improving.

I am playing with it a little and I wonder if I could expect greater redundancy (like three or more copies scattered) and block deduplication (that would probably require using a hash function instead or in addition of crc32 for block integrity checks)

The yum plugin (unfortunately, I am a Debian guy) looks very sweet.

Does anyone have any experience with Ceph? It sounds interesting, but is it reliable? Easy to configure and maintain?

It's still pretty experimental. Getting the kernel client into a released kernel has been a step forward, but Ceph isn't ready for production yet. It's getting closer, though.

I'm excited by the Python support in Perf.

How many megabytes is the current Linux kernel in its generic/default/full form (i386 or amd64, either goes)?

That is really hard to say. The source code is massive - hundreds of megabytes. The image created is tiny. It all comes down to what drivers and options are included.

Most generic kernel package included in Ubuntu is around 121mb. But it includes a lot of modules - see:

http://packages.ubuntu.com/lucid/amd64/linux-image-2.6.32-21...

Very few of these will actually be running on your system.

I work on embedded Linux and once build your own kernel with just the drivers you need, the image is tiny. I know the exact number of the top of my head but it was either a few mb or maybe even less than 1 mb. We had 256 mb of total system flash and we got our entire Linux distro on there easily.
