Nixpkgs unstable got a working build today and when I went to update I got a lot of major updates, but found an incompatibility between the Linux kernel at 5.3 and VirtualBox at 6.0.10.
I tracked down this bug in VirtualBox #18783 (Patch VirtualBox 6.0.10 for Linux kernel 5.3.y) – Oracle VM VirtualBox which patches the compile error I was seeing during my update. Fortunately I was able to just point directly at 5.2 kernel and resolve my issue. I was wondering what the practice is here, nixpkgs was the first place I looked when I ran into the issue.
Would opening a nixpkgs bug be the right thing here to track that issue and be a search target for anyone who might run into the same thing?
