docs: one rpm repo command that works on DNF4 and DNF5

[kixelated]

Follow-up to #4503.

Summary

The docs printed dnf config-manager --add-repo, which is DNF4 syntax. Fedora 41+ ships DNF5, which rejects it. #4503 fixed doc/setup/install.md by listing both variants, but when the block is pasted as a whole, one line always fails, and rs/moq-relay/README.md and rs/moq-gst/README.md still had only the DNF4 line.

All three now use the same single command:

sudo curl -fsSL https://rpm.moq.dev/moq.repo -o /etc/yum.repos.d/moq.repo

• It works on DNF4 and DNF5, and doesn't need dnf-plugins-core for config-manager.
• If the download fails, it exits with curl's status and leaves no file behind.
• It matches the command in moq.pro's quest/m1/gst-install-lines.md word for word.

This is the docs bullet of the rpm-signing quest planned in #4559.

Verification

Ran the command in clean fedora:40, fedora:41, rockylinux:9, and almalinux:9 containers. It exits 0, and moq-relay then shows up as available from the moq repo. Against a 404 URL it exits 22 and writes no file.

dnf install still fails with "The package is not signed", because the repo sets gpgcheck=1 and the RPMs are unsigned. The signing half of the #4559 quest fixes that and will land in a separate PR.

API / wire impact

None. Docs only.

MERGE

Positive, low-risk docs follow-up to the already-merged #4503. The install guide now labels DNF5 vs DNF4 with the right platform ranges and puts the Fedora 41+ path first, plus the useful dnf-plugins-core note for minimal DNF4 images. The relay and gst READMEs were still DNF4-only and would fail on current Fedora; aligning them to the same pair of commands is clearly worth it.

Complexity is tiny (comment labels + one prose line). No better alternative jumps out—duplicating the two-command pattern is clearer than linking out or inventing a wrapper. Unsigned-RPM install failure is correctly left to #4559.

Automated review by review (OpenAI)

Reviewed head: fa903dc.

No actionable new finding in the three-file documentation diff. The commands match the official DNF4 and DNF5 references, and the Fedora 41 boundary matches Fedora's DNF5 transition.

Direction: good and worth the small change. Updating both package READMEs closes the remaining DNF4-only examples, and the install-guide prerequisite helps minimal DNF4 systems. The direct-repofile download discussed on #4503 is a reasonable future simplification, but no wrapper or broader rewrite is needed for this fix. Separate copyable blocks would make choosing exactly one DNF command clearer; that is optional polish rather than a blocker.

The reported unsigned-RPM installation failure remains tracked by #4559 and is not introduced by this PR. API/wire impact: none.

Verification: inspected the full changed files and prior discussion, and checked upstream command documentation. I did not rerun the author's container installations or repository tests. This is a COMMENT review, not a merge approval.

Walkthrough

The setup guide and the moq-gst and moq-relay READMEs now instruct users to download the RPM repository file directly to /etc/yum.repos.d/moq.repo with curl. The previous dnf config-manager commands are removed. The package installation command in the moq-gst README is unchanged.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 3a9b6

The shared setup instructions leave openSUSE users unable to find the repository when installing packages. Add separate zypper instructions; the issue is limited to that documented platform path.

MERGE (re-review after push)

What changed since the last Grok review

The earlier review covered the dual dnf config-manager blocks (DNF5 + DNF4) plus the dnf-plugins-core note. This push replaces that with one command in all three files:

sudo curl -fsSL https://rpm.moq.dev/moq.repo -o /etc/yum.repos.d/moq.repo

That fixes the paste-the-whole-block failure (one of the two DNF lines always failed) and drops the config-manager / plugins-core dependency. Argument order matches moq.pro's quest/m1/gst-install-lines.md word for word. https://rpm.moq.dev/moq.repo returns 200; a 404 with -f exits 22 and leaves no file.

Findings

No issues found in the push.

Earlier review had no open findings. Unsigned-package install failure (gpgcheck=1) remains #4559's problem, not this docs PR.

Reviewed head: 3a9b6d5, compared with the previously reviewed fa903dc after separating base-branch churn.

Direction: good, and simpler than the previous DNF4/DNF5 alternatives. The same direct-repofile command in all three docs removes both config-manager plugin prerequisites and the copy/paste ambiguity. /etc/yum.repos.d is supported by both DNF4 and DNF5. The earlier DNF5-plugin finding no longer applies. No blocking finding in the three-file diff; no wrapper or broader rewrite is warranted. API/wire impact: none.

Minor correction to the PR description: please narrow “leaves no file behind” to the tested HTTP-error case. With these curl flags, a 404 returned 22 and created no file, but a local HTTP 200 response cut short after 18 bytes returned 18 and left those bytes in the output file. -f does not provide general failed-transfer cleanup, as the separate curl cleanup option documents. Tightening the claim is enough; this is not a reason to abandon the simpler command.

Verification: inspected all three changed files, prior discussion, repo configuration template, and upstream documentation; reproduced the two curl failure cases with curl 8.14.1 against a local HTTP fixture. I did not rerun Fedora/RHEL container installs or just check; Docker/Nix are unavailable here.

Merged as a squash onto main (e5239631b).

What landed: all three files now use one command that works on both DNF majors.

sudo curl -fsSL https://rpm.moq.dev/moq.repo -o /etc/yum.repos.d/moq.repo

• doc/setup/install.md
• rs/moq-gst/README.md
• rs/moq-relay/README.md

Verification:

• https://rpm.moq.dev/moq.repo is served (HTTP 200) and the body matches the template written by infra/rpm/publish.sh, including gpgkey=https://rpm.moq.dev/moq-keyring.gpg, so dnf imports the key itself and no keyring step is needed.
• The branch was rebased onto current main, which picked up fix(rs): pass _select seeds to awk via ENVIRON for BSD awk #4568. The awk: newline in string failure in the macOS job came from the _select recipe in rs/justfile and was pre-existing on main. It cleared after the rebase: macOS, Windows, Test, and Check all green before merging.
• just check passes locally.

Review:

• The first CodeRabbit finding (dnf5-plugins prerequisite) was written against the intermediate commit that still used config-manager. The final diff removes config-manager entirely, so there is no plugin to install. CodeRabbit withdrew it.
• The second finding (splitting openSUSE into its own section) is correct about the docs but pre-existing and out of scope here, and the suggested zypper addrepo command would be untested since the DNF paths were only exercised in fedora:40, fedora:41, rockylinux:9, and almalinux:9. Left for a follow-up that also settles the gstreamer1-moq package name on openSUSE.

No public API or wire impact. No package version bumps.
