From e6cbe6970f8e642a2229e0631eaa743fa86fcd29 Mon Sep 17 00:00:00 2001 From: Yu Watanabe Date: Tue, 9 Nov 2021 10:21:23 +0900 Subject: [PATCH] hostnamed: use /proc/device-tree to get chassis type From https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-firmware-ofw --- Userspace must not use the /sys/firmware/devicetree/base path directly, but instead should follow /proc/device-tree symlink. It is possible that the absolute path will change in the future, but the symlink is the stable ABI. --- Addresses the comment https://github.com/systemd/systemd/pull/20731#discussion_r744095262. --- src/hostname/hostnamed.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/hostname/hostnamed.c b/src/hostname/hostnamed.c index bcd2449861..e2c9f8ab67 100644 --- a/src/hostname/hostnamed.c +++ b/src/hostname/hostnamed.c @@ -302,7 +302,7 @@ try_acpi: } try_devicetree: - r = read_one_line_file("/sys/firmware/devicetree/base/chassis-type", &type); + r = read_one_line_file("/proc/device-tree/chassis-type", &type); if (r < 0) { log_debug_errno(r, "Failed to read device-tree chassis type, ignoring: %m"); return NULL;
