Man page section about "countme" isn't entirely clear on system age

[dmnks]

The "longevity bucket" reported in the countme flag is in fact based on the repository age, not system age as one would assume after reading the text:

countme
              boolean

              [...] The following 4 buckets are defined, based on how many full weeks have passed
              since the beginning of the week when this system was installed [...]

That's because the countme cookie file stored in /var/lib/dnf/repos/ is per-repository. This is by design, it's just that we never documented this properly.

The man page should instead say something along the lines of "when this repository was first accessed". I'll think about the exact wording a bit more and will submit a patch later.

(This came out of a discussion I had with some folks in the Fedora community about the countme feature.)

The intent of this value is to count time since installation. The system docs reflect that correctly. Can we invert the sense of this issue? That is, the problem isn't the documentation — the docs describe exactly what it should be doing. I'm sorry I missed that before!
