You don't need a management daemon running though, and get a complete virtualized kernel that can be customized if needed.

Ok, so IIUC, the main difference with firecracker versus docker is that processes are better separated from each other ("micro VM" instead of namespaces) and that one can run a customized kernel. But for e2e tests I've written, neither of these advantages mattered.

I do love the idea of taking a snapshot of a prebuilt database image and can see where this would really speed up the tests.
