I have yet to port my scripts (
https://bitbucket.org/znmeb/osjourno)
from 'yum' to 'dnf'. I'm not sure I am going to unless the live ISO
creation tools also switch. But I have tried both 'dnf' and 'yum'
manually during the F21 alpha and beta test phases. I think there were
cases where 'yum' said there were updates and 'dnf' didn't. And it
seemed like 'dnf' was slower.
My main use case is 'yum update' - I rarely use the Software tool on
the desktop.

Dear users of YUM and DNF,
I'm writing to you regarding a request for your feedback. I would be very grateful if
you could send me a brief description of how you use YUM or DNF currently or how would you
like to use it. I am particularly interested in the occurrences of "dnf/yum
install" calls in your scripts. What does these scripts do and what do they expect
when they call the "install" command in different situations?
Please share with me the use cases, not the description of the "install"
command. Think twice before you share something because I believe it's not as easy as
it might seem. As an example I think it might be something like:
- "I call YUM install, because I want to get given packages into my system and I
don't care whether it requires an upgrade or downgrade or what." or
- "I want to get them there but it should protect me against dangerous operations
like downgrades" or
- "I often make typos, so I expect that the program knows what I mean" or
- "it would be nice if it would literally perform the installation; if any of the
packages cannot be installed because of any reason, it should fail".
Not something like: "that's obvious that the install command should never
downgrade packages".
Please focus on *use cases*. The *real* (non-hypothetical) use cases. Not on the
command's name as it might also result in a new command (while preserving the
well-known install command together with an appropriate behaviour).
I don't mind if you send it offlist (or to another list). I think there is no need to
comment on anyone's use case. Every case is valid. Just not every case can be
supported.
Thank you very much in advance.
