Note that this is a follow-on project from the earlier Dettrace system, which was applied mainly to reproducible builds (as in the academic paper, https://dl.acm.org/doi/10.1145/3373376.3378519, and presented to the Debian Reproducible Builds summit):

And one cool part of it is this Rust program instrumentation layer:

It's good for building OS-emulator style projects or tracing tools.
