I have two installations of the Homebrew on a two different systems. One is older install, which follows
master branch, and one is newer, which follows
stable brach ('m talking about /usr/local/Homebrew repository). I’m troubleshooting one cask formulae I created and seeing different behavior depending on which system I will run: the system with master branch works flawlessly, one on stable, well — doesn’t work. So I am not sure what’s going on and unable to force newer install to force stay on master branch.
So question is: how to force branch on repository, so it won’t change after brew update?
