Words to the wise, DONT DO IT !
If you decide to do it, don't whine about it here!
If you read EVERYTHING before you do ANYTHING, and IF (that's a BIG IF) you can follow instructions (and most people can't) then everything will be fine. Otherwise, you will (probably) 'brick' your beautiful new Edison... a perfectly good perfectly functioning yocto fully embedded gnu/linux system the size of a postage stamp... but hey, you do whatever you feel is right... I tend to not let my feelings lead, but hey, ... Just sayin
hi, the reason is that you trade one set of problems for another; and, often the unit (the Edison) gets bricked in the process.
Yes, Ubilinux is more 'friendly,' has a better package manager, and has the entire debian support community... not to mention more binary packages available than yocto and opkg.
On the other hand, making xdk-daemon work on Ubilinux (with the rest of the Intel development kit) might be a fit. I'm not saying it won't work, I'm just saying that Intel has optimized their development kit to work with yocto.
The main reason I'm opposed to Ubilinux is that 'most' people end of bricking their Edison when they try it. I will tell you this, when it tells you to 'wait' two minutes at least in the middle of the process... YOU BETTER DO WHAT YOU WERE TOLD>>> I would go take a two - three minute walk at that point!
