From 56356c9deca6bc2142b8f69c94aea91ca47d81e9 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 26 Feb 2026 11:24:21 +0100 Subject: [PATCH] udev: tag DMI id device with "systemd", so that we can order units after it For various usecases it is useful to read relevant data from the DMI udev device, but this means we need a way to wait for it for this to be probed to be race-free. Hence tag it with "systemd", so that sys-devices-virtual-dmi-id.device can be used as synchronization point. --- rules.d/60-dmi-id.rules | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) diff --git a/rules.d/60-dmi-id.rules b/rules.d/60-dmi-id.rules index 10b1fe000c..ecea74ec60 100644 --- a/rules.d/60-dmi-id.rules +++ b/rules.d/60-dmi-id.rules @@ -2,24 +2,28 @@ ACTION=="remove", GOTO="dmi_end" SUBSYSTEM!="dmi", GOTO="dmi_end" +KERNEL!="id", GOTO="dmi_end" ENV{ID_SYS_VENDOR_IS_RUBBISH}!="1", ENV{ID_VENDOR}="$attr{sys_vendor}" ENV{ID_SYSFS_ATTRIBUTE_MODEL}=="", ENV{ID_PRODUCT_NAME_IS_RUBBISH}!="1", ENV{ID_MODEL}="$attr{product_name}" ENV{ID_SYSFS_ATTRIBUTE_MODEL}=="product_name", ENV{ID_MODEL}="$attr{product_name}" ENV{ID_SYSFS_ATTRIBUTE_MODEL}=="product_version", ENV{ID_MODEL}="$attr{product_version}" -# fallback to board information +# Fallback to board information ENV{ID_VENDOR}=="", ENV{ID_VENDOR}="$attr{board_vendor}" ENV{ID_MODEL}=="", ENV{ID_MODEL}="$attr{board_name}" -# stock keeping unit +# Stock keeping unit ENV{ID_PRODUCT_SKU_IS_RUBBISH}!="1", ENV{ID_SKU}="$attr{product_sku}" -# hardware version +# Hardware version ENV{ID_PRODUCT_VERSION_IS_RUBBISH}!="1", ENV{ID_HARDWARE_VERSION}="$attr{product_version}" ENV{ID_HARDWARE_VERSION}=="", ENV{ID_BOARD_VERSION_IS_RUBBISH}!="1", ENV{ID_HARDWARE_VERSION}="$attr{board_version}" -# chassis asset tag +# Chassis asset tag ENV{MODALIAS}!="", ATTR{chassis_asset_tag}!="", IMPORT{builtin}="hwdb '$attr{modalias}cat$attr{chassis_asset_tag}:'" ENV{ID_CHASSIS_ASSET_TAG_IS_RUBBISH}!="1", ENV{ID_CHASSIS_ASSET_TAG}="$attr{chassis_asset_tag}" +# Allow units to be ordered after the DMI device +TAG+="systemd" + LABEL="dmi_end"
