Greetings!
Newbie Cake user here. Happy to report I've recently managed to
compile and run Cake on my home router, a Raspberry Pi 3B+ (Kernel
Version: 4.14.62-v7+). Did not know of bufferbloat until quite
recently, and I learned a bunch. Today is day 2 on Cake, and quite
pleased with its outcome - thank you for curbing the menace!
I've jotted down the steps I took to get it setup. Until 4.19 becomes
common I hope it helps those who are looking to get Cake running on
their Pi's.
