I agree, and I understand how signatures work. But what am I missing?
It looks like in e.g. the Firefox package...

https://projects.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/firefox

...the only thing preventing a man in the middle from tampering with
the binaries as an Arch user installs Firefox are those SHA256 hashes.

I guess I just don't understand what happens when I type "pacman -S
firefox." Does that run the PKGBUILD on my system, or does it download
and install pre-compiled (and signed) Firefox binaries that were
created by one of the Arch developers using the PKGBUILD?

I have been assuming the former, that when I do pacman -S firefox or
pacman -S truecrypt, it runs the PKGBUILD on *my* system. Is that not
the case?

Thanks for your time,
