Re: [atomic-devel] Smaller fedora & centos images

[Muayyad AlSadi <alsadi gmail com>]

BTW: I'm considering writing my own "supervisord"-like in go (to make it single binary)

which unlike runit, s6 and others does not intend to be full init system (no ttys, no logs, no crons)

just like supervisord, it just process supervisor that allow you to run multiprocess container.

I'm considering an almost compatible ini syntax to systemd (so it could be called go-systemd, or yet another fake systemd)

why not just supervisord, because we are considering python-less micro base image for apps that does not need python specially go binary containers (ex. busybox, etcd, kube*, .. )

but I'm not sure if this is even a good idea or not

Try fake runtime which provides systemd (fake one indeed).

The largest chunk of this is that the httpd RPM pulls in systemd, and that's
going to be true presently for a lot of our RPMs.  So that's a whole subthread to this.

It'd be possible to teach micro-yuminst to just ignore requirements
on specific packages like systemd, while still allowing anyone who explicitly
wants them to pull them in.
