Yeah. There's definitely opportunity for some unit style tests in
virt-install, but this stuff will need a functional test suite in some
form, and some of it non-public for the windows stuff at least.

Dropping win2003 and earlier will simplify app implementations because
they can (probably) avoid the floppy requirement, like we discussed on
IRC. So I think that helps quite a bit. There's still definitely people
using winxp (despite being out of support microsoft just pushed a patch
update last week) but I don't think we need to support unattended
installs there anymore.

My opinion is mixed on killing off unattended support for EOL distros.
Doing a one time purge now is one thing, but going forward is the more
interesting bit. It would mean that working virt-install command line
invocations may break in the future which I never like. But I don't want
osinfo to be restricted by maintaining unattended compat with a ton of
old distros...

Maybe we can have an informal tier system based on what we test. So when
making unattended changes to git, we only functional test the non-EOL
distros. When a distro goes EOL we can fork off the install script to
fossilize it, so changes we make for Fedora 30 don't alter the config
for EOL Fedora 28.

Presumably if we do a one time test of say Fedora14 installing
correctly, then we fork the unattended install script, we can have
reasonable confidence that it will continue to work into the future
unless things change on the Fedora side. But we only do full install
testing with latest supported Fedora. But if for example fedora14 is
already broken then I'd say just drop it
