ci fails because Falco master CI was not able to push updated images (with the fix) because it got stuck at testing-packages of course.
Works locally against a Falco built from master:

./build/falco.test -falco-binary /home/federico/Work/falco/build/userspace/falco/falco -test.run TestFalco_Miscs_HotReload -test.v 
=== RUN   TestFalco_Miscs_HotReload
