I'm curious on why is it taking so long to add support for different runtime? I imagine it would be same for all of them?

This is interesting. Is there any challenge while working on this?

From my experience with firecracker, you need to send a signal to the VMM that can be used to indicate the process is "ready" (and the snapshot can be taken).

I assume that every runtime must be forked to add such signal right before calling into usercode

Thank you. This explains it.
