Using recent kernel (3.9 and later) features for (fast) SSD caching of (slow) ordinary hard disks.
== Detailed description == Recent Linux kernels support the use of Solid State Drives as caches for rotational hard disks. Because the high cost per GB for SSD devices this feature may bring the best of both: fast end big yet affordable storage capacity. Linux kernel 3.9 introduced dm-cache, kernel 3.10 introduces bcache.
== Scope == Proposal owners: Enable caching features in new kernels
These options are already enabled in the kernel.
Other developers: Support the caching features in their respective packages. Special focus should be on making the system boot from a cached root FS.
This is pretty generic. Which packages? Who is going to do the work here?
Release engineering: All packages should operate in close harmony te make this work. Only a rebuild of the relevant packages is required.
This doesn't make sense. We're doing a mass rebuild, so all packages are getting rebuild anyway.
I'm confused what this Change is actually for. It doesn't sound like an actual planned and targeted set of changes. It seems more of a nebulous "we should get people to do this" proposal.
