Nice one. It looks like execsnoop is not working here, any idea why?

--8<---------------cut here---------------start------------->8---
mathieu@meije ~/guix [env]$ sudo execsnoop 
Tracing exec()s. Ctrl-C to end.
ERROR: adding a kprobe for execve. Exiting.
--8<---------------cut here---------------end--------------->8---

Something missing in Guix System kernel configuration maybe?

Pushed anyway,
