@stefanoStefano Marinelli I really enjoyed listening (and reading). Neat summaries, especially your experience of real-world benefits.
With regard to FreeBSD and "separation between OS and packages", this is no longer true β the OS is packaged β however the vast majority of people will know what's meant π
A typical installation of FreeBSD-RELEASE for a desktop/laptop user might gain its packages from a trio of repos:
FreeBSD-base
FreeBSD-kmods
FreeBSD-ports
