From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

That is sound advice, the AUR is most definitely not a trusted source though. For the normal arch repos the people who put the stuff there are known, they work for the project, you're as likely to get malware from one of those as you are to read an article bashing gamespot in gamespot, the people in charge of putting the packages there are the ones with more vested interest in things working so they won't knowingly introduce malicious code (plus it's a handful of people who know each other by first name).
The AUR is a different story, because anyone can put stuff there it's very easy to have malicious code end up there. It doesn't happen that often because most of the time it's fairly obvious and it gets flagged straight away, plus if people start doing that people will migrate away from the AUR, so it's a high risk low reward situation. But as more and more people start to use Arch derivatives that come with the AUR enabled without understanding any of this it becomes a more rewarding thing to exploit.
like git repositories, AUR in its name itself says what it is, a User repository. its trust like repositories is fully based on how much you trust the user who uploaded it
In fact, most PKGBUILDs just clone git repos and build them
Yeah i think the aur is pretty much completely source based, with the exception of bin packages where they pull down a precompiled binary.
