nix and guix for Gentoo in 2025

August 19, 2025

Two years have passed since the last issue of ::nix-guix overlay updates. The overlay still ships latest nix-2.30.2 and guix-1.4.0 packages. One notable addition is lix-2.93.3!

Our list of contributors over past 2 years is:

dependabot[bot]
G-Src
Jiajie Chen
Kris Scott
Sergei Trofimovich
Vincent de Phily

There are no major user-visible changes. But a few things to note are:

sys-apps/lix was added to the family of nix-like package managers
sys-apps/guix is not masked any more as guile-3 was unmasked in ::gentoo!
old pre-meson version of nix are dropped
sys-apps/nix does not enable fallback if user namespaces fail to initialize. This should guard users from accidentally building non-hermetic packages (they are very likely to break on Gentoo for various reasons)
added USE=allocate-build-users to sys-apps/nix to use fully dynamic user builders (instead of requiring acc-user/ set of static users)
sys-apps/guix ebuild was ported to guile-single.eclass

Have fun!
