So lets say I am using Gnome 3.19.90. The 3.19.91 is released and you start build, which takes some time (12h? 24h? 2 days? Have no idea). In the middle of the build, the compose is done and it is pushed to the repositories. Now I do update of my computer and I get half of the packages of 3.19.91 but the second half is still at 3.19.90. They were never tested together and never expected to work together. There is probably hidden some ABI breakage. While the build continues and there are eventually build all 3.19.91 packages and everything will get into order, there is certainly substantial time during Gnome update when Rawhide is possibly broken (unfortunately this happened during every Gnome update in recent months). To minimize impact of the possible ABI incompatibilities, I can see several solutions: 1) Minimalist solution is to announce that you are building new version of Gnome and breakage can be expected. I would happily wait for the announcement of rebuild done to be sure that I get the whole Gnome update at once. 2) Use side tag for Rawhide builds 3) Specify more precisely the dependencies between Gnome project, e.g. gnome-terminal-3.19.91-1.fc25.x86_64 has to work only with vte291-0.43.91-1.fc25.x86_64 and nothing else, because this is how they were tested I hope you can make your choice, where the (2) is my favorite of course.
