Lightly "sandboxed" homebrew on macOS

brew is a bad neighbor

This isn't a guide about locking down homebrew so that it can't touch the rest of your system security-wise.

This guide doesn't fix the inherent security issues of a package management system that will literally yell at you if you try to do something about "huh, maybe it's not great my executables are writeable by my account without requiring authorization first".

But it absolutely is a guide about shoving it into its own little corner so that you can take it or leave it as you see fit, instead of just letting the project do what it likes like completely taking over permissions and ownership of a directory that might be in use by other software on your Mac and stomping all over their contents.

By following this guide you will:

Change ownership of selected older commits in Git
  1. Clone the repo.
  2. Use git rebase -i --root
  3. vim will open. Select the commits you want to modify by changing pick to edit. If you would like to change all the commits, perform the following replace: :%s/^pick/edit/g. This command changes all instances of "pick" at the start of lines to "edit".
  4. You will now be shown all the selected commits one by one. Each commit message will be displayed. You have two options:
    • If you would like to keep the commit author details the same, do a git rebase --continue.
    • If you would like to change it to a different name/email, do git commit --amend --reset-author. If --reset-author is specified, it will use the details from your git config. (If you need to specify an alternate name/email, you can do so with --author="John Doe <[email protected]>". If you would like to change the time to a previous date, you can do so with --date "2 days ago".)
  5. Do the same for all the commits and finish the rebase.
  6. Perform git push -f origin master to
