Fedora minimal installations

[Harald Hoyer]

In order to define the Base WG core package group and minimize minimal
installations for e.g. cloud images and the atomic spin, I created some
dependency lists:

There are so many definitions of minimum sets:

systemd: container boot
systemd + bash + login: container boot with login
systemd + kernel + bootloader + dracut: machine boot
systemd + ... + sshd + firewalld: network minimal

Here is a little script to generate the filelist (which apparently is extended
by dnf and kickstart with other default packages):
<https://harald.fedorapeople.org/pkgset/pkgset.sh>

So, if we start with systemd, then we'll get 112 packages at least for rawhide.
systemd (112 pkgs):
<https://harald.fedorapeople.org/pkgset/f24-systemd-requires.txt>

systemd+kernel+grub2+grub2-efi+grubby+dracut (142 pkgs):
<https://harald.fedorapeople.org/pkgset/f24-systemd-kernel-requires.txt>

systemd+kernel+grub2+grub2-efi+grubby+dracut+dnf (177 pkgs):
https://harald.fedorapeople.org/pkgset/f24-systemd-kernel-dnf-requires.txt


For a visualization I created some graphs for the systemd only dependencies:

<https://harald.fedorapeople.org/pkgset/systemd-all.svg>

and a reduced graph, which only displays one dep:

A couple of strange deps:
- libsemanage requires python
  (filed as <https://bugzilla.redhat.com/show_bug.cgi?id=1248002>)
- emacs-filesystem - do we really need that?
- info - do we really require that for every package, that ships info pages?
- krb5-libs requires gawk - why do libs require utils other than ldconfig?
- same with device-mapper-libs requiring device-mapper
- chkconfig - really?

please add your findings and/or file bugs
