Description

Hi team, thanks for open-sourcing the infra 🙏

I'm self-hosting and would like to build the whole stack from source, including Firecracker.
I noticed the customized Firecracker fork (e2b-dev/firecracker) is now archived, and fc-versions/build.sh defaults to e2b-dev/e2b-firecracker, which isn't publicly accessible.

A few questions on future plans:

  1. Is there a recommended public source for building a compatible Firecracker going forward, or is downloading the prebuilt binaries the intended path for self-hosters?
  2. Now that the fork is archived, will the Firecracker source (or prebuilt binaries) keep being published publicly for future versions?
  3. Any guidance on how self-hosters should track the fork against upstream over time?

Totally understand if this isn't a priority. Thanks for the great work!

Research direction

Start by reading fc-versions/build.sh and checking the archived e2b-dev/firecracker fork and the inaccessible e2b-dev/e2b-firecracker reference. Document the supported public source or binary path for self-hosters, future publication expectations, and how to track the fork against upstream.
