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.

Thank you for the explanation. Yes, I'm talking about the nix package manager, not about the operating system.
As far as I understand packages are built by less privileges users, but libraries and binaries are owned by the root user in the nix store.

What I wonder is wheter this could lead to root executing untrusted code. I will have several users installing packages and I can not trust that they will check every package. Thus I'd like to know whether I can trust the system to be resilient without careful attention.
If one user installs a modified version of a bin or lib it won't collide with the others.
