I have read Which minimal but extendable Linux distribution to choose but I'm using the word minimal in a slightly different sense: processes run at startup, not memory/disk space taken by the distribution itself.
I'm in the process of installing Fedora 24. After I install and reboot, there are close to 100 processes running, not including the bracketed process like '[kworker/6:1]' which I assume are magic and don't count.
Keep in mind, these are the processes running BEFORE I've installed anything using dnf or before I've made any changes to the system. Once I start adding packages and configuring the system, it gets worse.
I've tried to kill/stop/disable as many services as possible (see https://github.com/barrycarter/bcapps/blob/master/FEDORA), but I sense I'm on entirely the wrong track.
What minimal Linux distribution installs with the fewest processes running but still has a large dnf/yum/apt repository so I can install pretty much anything I want. In Fedora 24, for example, I do this (you do need to install a couple of repos to get this working):

(note that the above is all one line, I just added newlines to make it more readable).
and that's just for starters. With the possible exception of the Perl modules (which I believe should be handled by cpan), I want a distro whose repo has at least the above, and hopefully much more.
I'm currently using Fedora Core 11, so I prefer commands like yum and rpm, but am willing to switch if needed.
Just to clarify, I'm not looking for a command-line-only system. I do want to run X11 and fvwm2, but not the jillions of things Fedora 24 runs by default (I can provide a list on request).
I considered installing Fedora Cloud (https://getfedora.org/en/atomic/), but it appears to be specific to cloud environments and I wasn't sure if it was "real" Fedora that would work with Fedora 24 and compatible repositories.
