That was not obvious to me from the original bug report. Ideally I'd like to see full installer support but I don't know how much effort is involved. It is something that has been on my personal TODO list, and will get tackled sometimes now that jessie is out of the door.

Bug#774797: initramfs-tools: Include bcache.ko by default
Package: initramfs-tools Version: 0.116 Severity: normal Dear Maintainer, bcache is an SSD caching storage abstraction that's been in the kernel since 3.10 or so. For many modern laptops (e.g. many new Thinkpads) which ship with a small SSD intended for caching and a large spinny disk, bcache provides a good compromise between fast and cheap. However, installing Debian onto a bcache volume is still a bit of an obstacle course, and one catch-22 is that bcache.ko is not included in the initramfs by default. I'd argue that it should be. If it isn't a freshly installed system runs into the situation that it can't access its storage--bcache.ko sits on bcache storage, which you can't get to without having bcache.ko. I'm therefore suggesting that at the very least bcache.ko (and perhaps also bcache-tools) should be made part of the default initramfs image. Thanks!
