> The issue is package managers often can't handle replacing a symlink directly with a directory. By having a release in between, it becomes the same as a new file.
Doesn't that assume that the intervening package is actually installed?
If we just ship a renamed directory now, what are the chances that package managers will know to modify their package to remove the `__tuple` file so that a future version of the package can reuse that name? The chances seem pretty high to me.
For tarball-based installations, a temporary rename doesn't seem to allow a return to the original name without some additional ability to delete the original file.
I empathize with the issue you are facing. I don't have a lot of experience with package managers, but my understanding is that most have some ability to run code ahead of time. If nothing else, a package could have a dependency on another package that only contains post-install cleanup steps; e.g., a package that installs nothing and then runs a cleanup step to remove the `__tuple` file. Is this not a viable option for Gentoo?
