[yocto] Package Feature compile/runtime dependency

[Koehler, Yannick (HP Networking)]

The size of the resulting image of poky-tiny + systemd is a lot smaller than poky itself, even with the systemd kernel/glibc requirement set in.  The poky distro also pulls a lot more package into the mix that I do not need for my tasks.  I could go and disable those, but that is actually what poky-tiny also does for me already.

Poky-tiny allow me to go from small to my needs instead of the reverse which is harder to achieve as I would need to have a full understanding on how the dependencies works to save space, where the other way I need to learn how to get where I want but no more.

At least in my opinion, building with poky-tiny gives me currently around 1500 build tasks, where poky pulls over 2500, this shows how much more stuff "Poky" pulls in, no?

My hope, was that somehow, adding systemd to DISTRO_FEATURE would not only add the packages I need, but also add feature to some package like the kernel/libc that are required by such addition.

No, DISTRO_FEATURES don't change how eg libc and the kernel are built.  That said if you're building systemd, why are you using poky-tiny?  I doubt you'll see much gain from poky-tiny + all the pieces to make systemd work and plain poky (or the default distro configuration).
