Recently I have begun migrating my workstation and laptop from Gentoo to NixOS. There are a great deal of tradeoffs between the two operating systems. Before going into the details, consider where I’m coming from and why I moved away from Gentoo below. Why was I running Gentoo on workstations?? This is my heuristic for a good operating system: The Distro must provide facility to modify system packages and maintain their modifications in sync with the upstream distro.
