qemu is needed by lima, and bundled with Rancher Desktop. We essentially bundle the qemu code as released by the Homebrew project, but modified so that it can be installed into any location and not just
(by making all the dylib references relative to the executable instead of an absolute location).
It is possible, but a bit tedious to manually replace the bundled qemu. It would probably be best to file an issue on Github when the PR lands (and has been accepted into the Homebrew formula for qemu), and then we can update our dependency for the following release.
