Originally created by @elsbrock on GitHub (Jan 30, 2026).

Description

The Home Manager module hardcodes /bin/mkdir in the activation script, which breaks on NixOS systems where /bin/mkdir does not exist (only /bin/sh is guaranteed on NixOS).

Location

File: nix/modules/home-manager/openclaw.nix

The openclawDirs activation script uses /bin/mkdir -p ... and the openclawConfigFiles script uses /bin/ln -sfn ....

Error

/nix/store/xxx-activate: line 323: /bin/mkdir: No such file or directory

Reproduction

  1. Deploy nix-openclaw on a NixOS system using the Home Manager module
  2. Observe activation failure during home-manager switch

Fix

Replace absolute paths with bare commands (available on PATH during HM activation):

- /bin/mkdir -p ...
+ mkdir -p ...
- /bin/ln -sfn ...
+ ln -sfn ...

Or use explicit Nix store paths like ${pkgs.coreutils}/bin/mkdir.

Workaround

system.activationScripts.binMkdir = ''
  mkdir -p /bin
  ln -sf ${pkgs.coreutils}/bin/mkdir /bin/mkdir
  ln -sf ${pkgs.coreutils}/bin/ln /bin/ln
'';

This was identified a couple weeks ago. Been hoping for a fix since https://github.com/openclaw/nix-openclaw/issues/5

[🤖 this message brought to you by codex] should be fixed in b2721d72 (HM activation uses run + coreutils). Closing for now — come and yell at me in #golden-path-deployments on discord if you're still having issues! Stability work continues; we are making this better every week.
