From fbc5093649b17b65a5db6caa252f7d3aa99f94d0 Mon Sep 17 00:00:00 2001 From: Robert Helgesson Date: Mon, 19 Aug 2019 16:05:44 +0200 Subject: [PATCH] hooks: add moveSystemdUserUnitsHook This hook moves systemd user service file from `lib/systemd/user` to `share/systemd/user`. This is to allow systemd to find the user services when installed into a user profile. The `lib/systemd/user` path does not work since `lib` is not in `XDG_DATA_DIRS`. --- doc/stdenv/stdenv.xml | 13 ++++++++++ nixos/modules/config/system-path.nix | 1 + .../setup-hooks/move-systemd-user-units.sh | 25 +++++++++++++++++++ pkgs/stdenv/generic/default.nix | 5 +++- 4 files changed, 43 insertions(+), 1 deletion(-) create mode 100755 pkgs/build-support/setup-hooks/move-systemd-user-units.sh diff --git a/doc/stdenv/stdenv.xml b/doc/stdenv/stdenv.xml index f97c2a145af..e85e2ccb0ec 100644 --- a/doc/stdenv/stdenv.xml +++ b/doc/stdenv/stdenv.xml @@ -1834,6 +1834,19 @@ addEnvHooks "$hostOffset" myBashFunction + + + move-systemd-user-units.sh + + + + This setup hook moves any systemd user units installed in the lib + subdirectory into share.
