stuebinm 6afb255d97 nixos: remove all uses of lib.mdDoc
these changes were generated with nixq 0.0.2, by running

  nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix

two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.

Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.

Some NixOS packages provide debug symbols. However, these are
not included in the system closure by default to save disk
space. Enabling this option causes the debug symbols to appear
in {file}`/run/current-system/sw/lib/debug/.build-id`,
where tools such as {command}`gdb` can find them.
If you need debug symbols for a package that doesn't
provide them by default, you can enable them as follows:
nixpkgs.config.packageOverrides = pkgs: {
hello = pkgs.hello.overrideAttrs (oldAttrs: {
separateDebugInfo = true;
});
};
'';
};
};
config = mkIf config.environment.enableDebugInfo {
# FIXME: currently disabled because /lib is already in
# environment.pathsToLink, and we can't have both.
#environment.pathsToLink = [ "/lib/debug/.build-id" ];
environment.extraOutputsToInstall = [ "debug" ];
environment.variables.NIX_DEBUG_INFO_DIRS = [ "/run/current-system/sw/lib/debug" ];
};
}
