Allow the ability for a system administrator to use
HOMEBREW_BREW_WRAPPER
andHOMEBREW_FORCE_BREW_WRAPPER
variables to enforce the usage of a particularbrew
command for non-trivial (e.g.brew --prefix
is considered trivial, it doesn't need to write to the prefix) Homebrew commands.This also introduces a
HOMEBREW_ORIGINAL_BREW_FILE
variable for some internal usage;HOMEBREW_BREW_FILE
was being used internally for both "how should we shell out to Homebrew" and "what should we use to check permissions on Homebrew".HOMEBREW_ORIGINAL_BREW_FILE
is now used just for the latter case.Inspired by conversation in Homebrew/homebrew-bundle#1551 which suggested this was worth fixing in wider than just
brew bundle
.
