As described, Fedora 27 has a curl-minimal package that comes in to
satisfy the rpm package dependency. It conflicts with the "real" curl
package -- which is so commonly installed (by infra elements, etc)
that this becomes an annoying problem. Just pre-install the full curl
package.
Fedora 24 is old enough to not worry about, so remove some old
workarounds to make the flow a little simpler.
