Do you have example settings for systemd to start s6-svscan?
I don't, sorry. I never bothered to learn the syntax, and I kindaomitted systemd from the https://skarnet.org/software/s6/s6-svscan-not-1.html
page on purpose. But I'm sure somebody somewhere has such an example, and if not, it really shouldn't be too hard, because it's a very simple service. -- Laurent
