Hi - zeroserve Caddy compat works by compiling Caddyfile to C. Technically I can keep the compiler in a separate binary/repository - but it just feels unnecessary.

zeroserve only understand eBPF at runtime. It's always the source-of-truth.

Hi, thanks!

Will implement forking + SO_REUSEPORT. I've been using nftables for things like this so haven't needed it for myself yet :)

Hi, author here - a few critical pieces of this, like async-ebpf, were written long before those coding agents were released. I use AI assistance a lot when creating zeroserve itself, but I manually check AI output and take responsibility for it :)

> Firstly, can there be an easier way to stop a microVM mid execution in this single executable bottlefire format and then rerun that and it would start mid execution. (something akin to how criu does it?)

Not yet - Firecracker supports snapshotting so this should be doable though!

Some cloud providers - like GCP and DigitalOcean - do support nested virtualization, and they work pretty well with Firecracker. Using VM migration to run stable workloads on spot instances sounds very interesting :)
