Look forward to ye olde uncle Lennart's old-timey sales pitch.

I'm gonna summarize the Varlink talk: DBus is, and I quote, "very very very complex" and his system with JSON for low-level IPC is, in fact, the best thing since sliced bread and has no significant flaws. It works basically just like HTTP so the web people will love it. Kernel support for more great shit pending! I'm not sure where the hardon for a new IPC system with lernel (keeping that typo) support is from, but he's been trying for 15 years now. AFAICT, the service discovery problem could be solved by a user space service without much trouble. I mean if the whole thing wasn't an exercise in bad technological taste.

I do not share your view of old timey sales pitch, at least for the talk about systemd nspawn OCI container support.

If anything, that talk was a tad low effort, with even dismissive answers — "Yes" and "No?" as full answers to audience questions, with no follow up?! Still very informative though!
