1️⃣6️⃣ Here's the 16th installment of posts highlighting key new features of the upcoming v256 release of systemd. (Sorry for dropping the ball on posting these for a while!) The last feature I want to discuss in this series of postings is the new "capsule" concept of systemd v256. systemd can be invoked in two contexts: as a system manager, i.e. PID 1, where it manages, well, the system. And as a user manager where it runs services for a specific user.
