There's also other components; while etcd and flannel could be thought of as
"kubernetes enablers"
and fall under the same umbrella, they are distinct projects with their own
release cycle.
Also, it's worth keeping in mind that it would be nice if we made more use of
newer systemd
features, which is a big project with its own cycle.
Finally, I'll also note that rpm-ostree does link to the packaging stack
(libhif -> hawkey/librepo)
which necessarily implies some ties to the cycle of those components.
Nod, it's just hard to list all of those out. Perhaps in the future we should
call them "Atomic components."

Not just build failure, but runtime failure.
This one's new to me, I'm aware of the issues with building images but I
was under the impression that the composed OStree was still happening successfully
whenever rawhide was building. Are you saying there are sometimes where upgrading
to those trees would have resulted in an unbootable system?

I'm not actually doing the ostree side very often right now, but that will
hopefully
change as more user-visible features land.
Anyways, the bottom line for me on this is:
Before we can do two weeks, we need to be able to do rawhide. There are
parts
of this that work (tree and cloud images are carryover from F22), but the
installer
and PXE-to-Live are blocked on:
