I don't mean to start an argument and this is a question out of honest
curiosity. I'm not familiar with the details of yum or dnf's requires
resolution, but are there really ambiguities in the dependency tree that
have multiple resolutions that are "valid" (like the ruby example you list
in the blog post)?

In my mind, "non-standard but works" is better than "standard but broken".
Especially, when the error is a bit hard to decipher and tracking down a
solution can take a while (at least in my case it did). Basically, I think
that one of the following solutions would be helpful:
1) Change EL to default to using yum so it "just works", or
2) Change the error message on EL to indicate why it's not working and
where more info can be found.

Thanks,
Dave
