I am a Debian user and I reported a wish to the wishlist-bugs to

I just wanted to inform you about that, because I think that you are
an important piece that could solve the clue by adding support to
bcache partitioning into parted.

This is the message I wrote:

Dear Maintainer,

Last kernel versions have added bcache to the system. It allows to use
an SSD drive as a cache for a -for example- a disk drive partition.

A common installation is /dev/sda as the main disk drive and /dev/sdb as a
cache drive for it. After a configuration like this, one gets the /dev/bcache0
device to mkfs the filesystem  on it, in a similar way to LVM or RAID. Even
more, bcache can be combined with these.

It would be nice if the installer gave these options to configure, for example,
at the moment, in an expert mode install. It would require bcache-tools at boot
and bcache as a module in the kernel.

You have more info at http://bcache.evilpiepirate.org/ and in kernel source at
