A modern, delicious implementation of the Nix package manager, focused on correctness, usability, and growth — and committed to doing right by its community
This line has been this way since it was written, in 9e08f5efe
in 2006.
I think it was just a small mistake then; Eelco's thesis earlier
that year says the permission on each file is set to 0444 or 0555
in a derivation's output as part of the build process. In any
case I'm pretty sure that's the behavior now.
Nix is a new take on package management that is fairly unique. Because of its
purity aspects, a lot of issues found in traditional package managers don't
appear with Nix.
To find out more about the tool, usage and installation instructions, please
