Fedora CoreOS is too large

[bgilbert]

Random observations:

• We're shipping systemd-bootchart, adcli, libxkbcommon, and cracklib-dicts. I think these are all coming in via recommends.
• We're shipping cups-libs and 64 MB of GeoIP database.
• We could drop man pages and info docs, but that would only save us ~12 MB.
• We're explicitly shipping dnsmasq, which seems like it could go.

Maybe we should try disabling recommends and seeing what happens.

We're currently shipping man pages and info docs, but not man(1) or info(1).

coreos/fedora-coreos-config#98 drops dnsmasq, man pages and info docs, and some recommends including the bulk of GeoIP.

Locale related files might be able to be removed/stripped as well. I think Fedora comes with full locales instead of generating only necessary one.

grub2-{pc,efi} pulls in grub2-tools-extra, which pulls in freetype, which pulls in libpng.

Could we consider moving to providing a standard means to install 3rd party packages outside of overlays, such that those packages can be called in via ignition. Toolbox would only be one of such packages.

I set about developing such an install mechanism which includes a script and a unit that could be included as standard (or enabled via ignition)

Since https://bugzilla.redhat.com/show_bug.cgi?id=2006063 is now closed we are no longer shipping cracklib-dicts

[dustymabe]

and just by inspection it seems like cups-libs systemd-bootchart and libxkbcommon are no longer shipping either.

[dustymabe]

Maybe we should close this out?

FYI: recommends were disabled and other things removed in coreos/fedora-coreos-config#98
