Difficulty pinning packages in development

[cfcs]

After this was introduced in 8ad2bcc I'm struggling to pin local development branches.
Here's what I tried:

$ opam pin add -n dns --dev -k git git+https://github.com/roburio/udns.git
# ...
$ opam pin add -n dns-client --dev -k git git+https://github.com/roburio/udns.git
# ...
$ opam install dns

<><> Synchronising pinned packages ><><><><><><><><><><><><><><><><><><><><><><>
[dns.1.1.1] no changes from git+https://github.com/roburio/udns.git

[NOTE] Package dns is already installed (current version is 1.1.1).
$ opam install dns-client.1.1.1
[ERROR] Package dns-client has no version 1.1.1.
$ opam install dns-client

<><> Synchronising pinned packages ><><><><><><><><><><><><><><><><><><><><><><>
[dns-client.~dev] no changes from git+https://github.com/roburio/udns.git

Sorry, no solution found: there seems to be a problem with your request.

No solution found, exiting

My local workaround was:

$ sed -i 's/"dns"/#&/' dns-client.opam
$ opam pin add -n dns-client --dev '.'
$ opam install --working-dir dns-client

Is there a more ergonomic way to work with a development version?

you can as well opam pin add dns-client.2.0.0 --dev (for all packages, include a version number) to avoid running into conflicts.

Thanks, this worked!
