So I'm rebuilding my storage server. For stability, I want to use Ubuntu server 14.04 LTS as the OS. However, I'm planning to use Btrfs with RAID 5, and this has been greatly improved in kernel 3.19. So I want to use that kernel with 14.04.
I know that 3.19 is the kernel that will be used in 15.04, and is scheduled to be released in August as a HWE kernel and the default for 14.04.3. But I need to build this server now.
I don't want to get into funky custom set-ups that will break things in future. So what is the most trouble free way I can use that kernel now on top of a 14.04.2 installation, that can be easily reverted to standard in August, when I can dist-upgrade to 14.04.3 and get the kernel I want as standard?
