This is not using OO as it could: have a class that does what we need and zwo small sub-classes: one for yum and one for dnf. This would avoid the branching we are seeing here. It's probably ok because I don't expect more variation here.

Yes, it can be.
As you already point out, this is only tiny diff here between yum and dnf.
Even with class, we need branching which class to use anyway, so I prefer to just this none-OO styple, does this make sense? (If more and more variation comes, then we can use OO later.)
