My linux config and rc files https://git.sommerfeld.dev/dotfiles/atom/nix/vm.nix?h=master 2026-05-22T09:41:24Z 2026-05-22T09:41:24Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-22T09:41:24Z urn:sha1:b8dce5c1561f27dbd56f5fc34eff0b42fa973bb7 Add dot_config/tuicr/config.toml with theme = "gruvbox-dark". Symlinked from nix/vm.nix per the symlink invariant so the same config applies on both host (via chezmoi) and VM (via home-manager). 2026-05-22T09:41:23Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-22T09:41:23Z urn:sha1:5070187ab99b09ca22514f228f079d032745bde8 The VM doesn't run chezmoi, so every config the host gets via chezmoi must reach the VM via a nix symlink. Audit found gaps for tools whose binary IS in common.nix but whose dot_config tree was unlinked: bat, lsd, yazi, ripgrep, fd, wget, npm, ipython, gdb, clangd, ccache Plus the new tuicr claude-code skill (under ~/.claude/skills/tuicr/, NOT ~/.config — uses home.file instead of xdg.configFile). Reorganises the block by category and adds an INVARIANT comment pointing at the rule in .github/copilot-instructions.md. GUI/wayland-only tools (sway/mako/waybar/fuzzel/mpv/zathura/etc) stay unlinked: the VM is headless. 2026-05-20T12:56:11Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-20T12:56:11Z urn:sha1:639f3cb82ef9f1e6dd0b47cf506ff3c09fd4a5a7 Per user decision: on the Arch host, chezmoi remains the single deployer of $HOME dotfiles. nix/common.nix's xdg.configFile + sshConfig activation + .zshenv home.file block was causing home-manager to fight chezmoi on every nix-switch, materializing .backup files for nvim, zellij, zsh, git, ghostty, direnv. Resolution: - nix/common.nix: drop the entire deployment block, drop the my.dotfilesPath option, drop the let..in dotfiles/link helpers. Module is now deployment-agnostic: only installs packages. - nix/host.nix: drop my.dotfilesPath; explicit comment that chezmoi owns dotfile deployment on the host. - nix/vm.nix: gains everything previously in common.nix's deployment block — xdg.configFile (nvim/zellij/zsh/git/ghostty/direnv), home.activation.sshConfig, home.file.".zshenv". The 'dotfiles' let-binding (= $HOME/.local/share/dotfiles) and 'link' helper move here too, since they're vm-only now. Host runbook unchanged (`just sync`); first run after pulling will just be a no-op nix-switch instead of a backup-file storm. 2026-05-20T12:56:10Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-20T12:56:10Z urn:sha1:58f2d61be4c55c7cf7bdbb12f3fed6794e7481b5 - common.nix hardcoded the runtime dotfiles checkout to ~/.local/share/dotfiles, which is correct for the remote-dev VM but not the Arch host (where the canonical clone lives at ~/dotfiles). ssh activation was failing with 'cannot stat /home/sommerfeld/.local/share/dotfiles/private_dot_ssh/config' on every host nix-switch. Promote the path to a typed option (config.my.dotfilesPath) and set it from each profile: nix/host.nix -> $HOME/dotfiles nix/vm.nix -> $HOME/.local/share/dotfiles common.nix now wraps its config in 'config = { ... }' so the options can sit alongside. - dockerfile-language-server-nodejs was renamed in nixpkgs to dockerfile-language-server; pick up the new name to silence the evaluation warning (the rename will eventually become a hard error). 2026-05-20T12:56:09Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-20T12:56:09Z urn:sha1:e66aa35ea314f522a2cdfaebdacf87894a44bd04 Replaces Mason entirely (phase p6 of the nix migration will rip out mason-tool-installer and friends). The set tracks the previous ensure_installed list in nvim's lsp.lua, with five niche tools dropped per the migration plan: - groovy-language-server, npm-groovy-lint - nginx-language-server, nginx-config-formatter - systemdlint systemd-lsp is renamed to systemd-language-server (the nixpkgs attr name). codelldb is replaced by lldb-dap (upstream successor, ships with pkgs.lldb); dap configs switch in phase p6. Drops jre, basedpyright, cargo, rustc from vm.nix — they only existed to work around Mason quirks on Ubuntu 20.04 (uv-python wheel incompatibility, source-build needs). With Mason gone, basedpyright comes from nixpkgs cleanly on both profiles. Phase 5 of the nix-on-host migration plan. 2026-05-20T12:56:09Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-20T12:56:09Z urn:sha1:de5146c7976e1fb38e8d1f82c30544462d881100 Restructures the Home-Manager profile to support both the Arch host and the Ubuntu remote-dev VM from the same flake. - remote-dev/ → nix/ (hard rename; .chezmoiignore updated) - home.nix split into common.nix (shared), vm.nix (Mason runtime carve-outs + podman stack), host.nix (gpg scdaemon delegation to system pcscd) - flake.nix exposes homeConfigurations.{vm,host} via a mkProfile helper - rj alias in dot_zshrc updated to ~/.local/share/dotfiles/nix - bootstrap.sh / justfile updated to use #vm against the new path The split is behaviour-preserving for the VM: vm.nix + common.nix together carry the same package set as the previous home.nix. host.nix is provisioned but not yet wired into bootstrap (phase p8). Phase 1 of the nix-on-host migration plan.
