Have puppet, chef, ansible, salt, etc. been taught how to use "dnf" to
install packages? I think it would be a shame to force all this
software to do s/yum/dnf/ or to have to conditionally code for these
differences based on OS release or the presense of yum vs. dnf. Why
not just keep the command name the same with no nag message?
I would expect puppet/chef to start using the library rather than direct
access to the binary.
And for ansible, I think the patch is quite simple, just add 2 lines.
I guess we can start right now to get stuff merged.
