Hi,Recently I need to write a supervisor for my service that
consist of a few processes.And I encounter the systemd in my environment. In
the first place I thought I would like to write some Unit files for systemd and
I will be done.But it proves that I am wrong. Systemd is a very complex and
even though I spent a lot of time to figure out what directive to use, I still
dont have confidence that I did it correctly.Then I look at one of the idea
behind the systemd is that systemd will have a full dependency graph for
running service.Is it a good idea? I asked myself. And my answer is no. Becuase
processes are living context and anything can happen to it. If a process needs
to take a consideration of existence of other process, that it should do it by
its own.It is not like a build dependeny that can be bakced by a file system
and is staic in a sense you can always go to states x,y,z like git commits.Any
comments on my thought? Should the system manage the dependencies of service at
runtime in a global scale?Best,Robin
