I've implemented a patch that allows makepkg to return discrete error values for different errors. This is based on the comments scattered throughout indicating that at some point, somebody intended to implement this.
As a side benefit, it also closes [FS#54204][], since being able to return a recognizable error from a failed install_package means that we can still do clean-up even if this function fails. Cons: That's a lot of different types of error. As always, I welcome your critiques! iff Links: [FS#54204]: https://bugs.archlinux.org/task/54204
