The automation should never rerequest reviews from users that already
reviewed the changes, which is what was happening before this change:
https://github.com/NixOS/nixpkgs/pull/347354#event-14570645380
Also reorder the arguments to make more sense
Also post a comment in case base branch is wrong
This guides newcomers in how to smoothly handle the potentially scary
situation of having thousands of commits listed in a PR.
While CI shows the same, people might not even look at CI if the PR
looks botched.
Found using https://github.com/serokell/xrefcheck, which unfortunately
can't trivially be enforced in CI because we also have the manual markdown
files that need post-processing to be valid
Everything gets moved into the `ci/` top-level directory.
We keep behind `maintainers/scripts/check-by-name.sh` and `pkgs/test/check-by-name/pinned-version.txt` as they are going to cause CI errors and confusion until we get all the way through the various channels.
They'll be removed in about a week or so.
This script only needs to make sure that the revision has the relevant
packages built, it doesn't necessarily need to be a channel version.
This commit makes it possible to set the revision explicitly when
calling the update script.
This is needed such that in the next commit, we can re-use the same
version from a shell.nix, allowing people to have a guaranteed matching
nixfmt version.
