Please do not tell me that I want to write a unit file when the *entire* ecosystem takes command lines just fine. I have hundreds of dockerfiles that have entry points - why do I need to write unit files for them? I have command line tools that generate docker images... with command lines - why would I want to write unit files for them?
Also, dumb-init is not an init system. It's a signal proxy. On Mon, Mar 6, 2017 at 9:55 PM, Scott McCarty <smcca...@redhat.com> wrote: > I am skeptical of any "resource" argument against systemd.
