- Output `brew doctor` and `brew install` messages noting this configuration is (currently) unsupported and encourage use of Rosetta instead
- Output Rosetta 2 usage in `brew config` on ARM (whether in Rosetta 2 or not)
- Check the architecture of (newly installed) dependencies and ensure they are using the correct architecture.
- Don't allow installing macOS Intel Homebrew in macOS ARM Homebrew default prefix (and vice versa
- Actually write out the architecture of dependencies to the tab rather than generating and throwing them away
- Set and document the expected default prefix for macOS Intel Homebrew, macOS ARM Homebrew (`/opt/homebrew`) and Homebrew on Linux
While we're here:
- Don't say Big Sur is a prerelease version but still make it clear we
don't support it (yet).
- Don't reference non-existent IRC channel
- set `Formula#force_bottle` from `FormulaInstaller`
- refuse to install non-bottled formulae with `--force-bottle`
- raise exceptions on fetch/pour failures if `--force-bottle is passed.
While we're here:
- use `CannotInstallFormulaError` for some `RuntimeError`/`odie`
Fixes https://github.com/Homebrew/brew/issues/8866.
The way we currently handle @-versioned formulae linking is pretty
labourius:
- it requires extensive use of `link_overwrite` to avoid the `link`
stage failing on certain install/upgrade scenarios
- we teach people to use `brew link --force` whenever they wish to
link a versioned formulae when it's pretty obvious what's expected
in that situation
Instead, let's:
- automatically unlink other versioned formulae when linking a
versioned formula (either through `brew link` or `install`/`upgrade`
/`reinstall`)
- notify the user what we've done (with the same messaging as if
they had run `brew link` manually)
Ensure that we don't try to check for broken linkage in a keg that
doesn't exist. Furthermore, fix the reason we checked for the keg that
doesn't exist by `Formula.clear_cache`.
While here, I noticed that there was other methods of caching at use in
`Formula` so consolidate them to be consistent.

Adding this in `dev-cmd/ruby.rb` allows us to suppress warnings like:
```
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/language/python.rb:8: warning: Insecure world writable dir /home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/shims/scm in PATH, mode 040777
