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
Other developers: Support the caching features in their respective packages.
Special focus should be on making the system boot from a cached root FS.
Release engineering: All packages should operate in close harmony te make this
work. Only a rebuild of the relevant packages is required.
Policies and guidelines: No changes I think.
