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!
