Question is updated. Now bcache is part of the standard OS compilation.
So it should be easy to install that now. I'll just order some SSD and some big HDD.
Where can I found it?
I found on the net and it's all too complicated.
http://bcache.evilpiepirate.org/ for example seems like the official page for bache. Yet nothing is found there. How to install? How to set up? Nothing
Some tutorial says that I have to make bcache, where can I download it? How do I download it?
Some says that I have to recompile kernel. Some tutorial doesn't mention that. Which one is right?
Nothing makes sense.
Okay there is git. Then what? What to do with git?
