Yes, I would *guess* it involves:
- modifing anaconda to allow cache device designation during installation
(this is more important with bcache, as it needs special formatting;
dm-cache can be disabled/enabled on the fly)
- modify dracut to properly attach bcache in initramfs
- integrate dm-cache handling with local-fs.target
- finishing SSD caching layer for btrfs
- (...) ?
