They did (assuming that what you wrote about the s6 case > means that the system more or less reconstructed itself). I am glad some of you can tell more than I can about this, and since you did I tried my weirdest of setups. This is Adélie adelielinux.org installation on HD. Although it is confusing to me how they set this up still, after months of following its development (beta3), there is sysvinit on the first steps of booting then OpenRC takes over, and then s6-supervisor handles everything running. It is like a fruit punch in my eyes. For those that don't know this is built on musl. # kill -9 -1 on tty1 brought me back to tty1 login screen with 5 more ttys active. So everything is respawned almost instantly to a system just like it had just booted. Doing the same from terminal on X had the same exact outcome. > Thanks, > G. One of the reasons I am trying to learn more about init in general and porting s6 to a different system is to use either Adélie or Void-musl and have pure s6 on them. Recent efforts with void failed, except for using arch kernel building and installing Obarun's pkgs into void. Not very clean but works for months. Dracut is a thing I still need to learn about as obstacle #1. Both s6/s6-rc and 66 pkgs are available through void's repositories but s6-rc has been modified and I haven't been able to get it to work. Void uses arch-like /bin /sbin --> /usr/bin, Adélie has more traditional 4 separate directories.
