From b4b02e8e824679b8890ea5eb827d609a738f49c7 Mon Sep 17 00:00:00 2001 From: itexpert228 <67105314+fdaser1337@users.noreply.github.com> Date: Sun, 15 Mar 2026 15:24:24 +0300 Subject: [PATCH] feat: Add Nix-style binary cache, Linux sandbox, pacman UI, thermal management, fakeroot tests - Content-addressable store (CAS) like Nix for fast lookups - Binary cache system with remote support - Linux chroot sandbox for isolated builds - Pacman-style UI with progress bars and colors - Temperature-aware parallel builds - fakeroot integration tests - Update .gitignore for Docker and test artifacts Implements LFS-optimized build pipeline with proper fakeroot support. --- .gitignore | 22 ++ cmd/install.go | 273 +++++++++++++++---------- cmd/lfs_linux.go | 133 ++++++++++++ fakeroot_test.go | 213
