        But note that the installed repo file will likely need a manual modification.

See this tmt-run.log

Expected behaviour

DNF should try to install from the correct rhel based repository and not from RHEL.

Proposal

The tmt-run.log from above shows this solution:

dnf copr enable @fedora-llvm-team/llvm-snapshots-big-merge-20240526 <repository>

We can apply this solution to the way that we enable the snapshot repository here:

prepare:
  - how: install
    copr: "@fedora-llvm-team/$COPR_PROJECT"

The trick is to pass an additional parameter like so:

prepare:
  - how: install
    copr: "@fedora-llvm-team/$COPR_PROJECT $COPR_CHROOT"

$COPR_CHROOT can be set as an environment variable similar to COPR_PROJECT to the chroot for which we make the request.
