at Parabola GNU/Linux, a recent entry in the GNU list of free
. "Parabola developers chose a refreshing approach to limiting the availability of non-free software while maintaining the ability to use Arch mirrors: all the "liberated" (built with special options or otherwise stripped off the non-free parts) packages are included in a separate "libre" repository; the blacklisting of non-free packages is done with a virtual "your-freedom" package that doesn't install any files but conflicts with a long list of packages. Installing this package makes pacman (package manager) remove all the non-free software to resolve conflict or replace it with free analogues if required.
