I don't think you need to do all of this. With

```
sudo dnf repoquery --repo=rawhide -q --whatrequires dcmtk | xargs sudo dnf repoquery
--repo=rawhide -q --latest-limit 1 --source
```

AFAIK, dnf repoquery is smart enough to figure out the virtual provides
by itself. You can install fedora-repos-rawhide on a stable Fedora
release to get the rawhide repo definitions. (They're disabled by
default, so don't worry about your packages getting updated to rawhide
versions!) `--release rawhide` is not what you want. On my system, it
adds a few seconds to the script's execution, as it tries to load the
rawhide version for all of the enabled repositories. You only want to
query the rawhide repo itself.

A better version of the above would be

```
sudo dnf repoquery --repo=rawhide -q --whatrequires dcmtk | xargs sudo dnf repoquery
--repo=rawhide -q --source | pkgname | sort | uniq
```

which just includes the *names* of the affected source packages. This is
most likely what you want for doing rebuilds.

If you're trying to find which source packages *Build*Require something,
you can use

```
sudo dnf repoquery --repo=rawhide{,-source} -q --whatrequires dcmtk-devel | grep
'\.src' | pkgname | sort | uniq
```

You can add --recursive to either command if appropriate.

You can also add a .repo file for the koji buildroot repository and
query that

```
$ cat /etc/distro.repos.d/koji.repo
[koji]
name=koji
baseurl=http://kojipkgs.fedoraproject.org/repos/rawhide/latest/$basearch/
enabled=0


[koji-source]
name=koji-source
baseurl=http://kojipkgs.fedoraproject.org/repos/rawhide/latest/src/
enabled=0
```

I believe Miro uses this for the FTI bugs. It tends to be more accurate,
especially when there hasn't been a compose for a couple days. If this
is something people are interested in, I think it's worthwhile to
include this repo definition in fedora-packager.
