On Linux, most golang programs do not run as root (or at least, they should not), by default, the kernels uses strict permissions, so most userland programs cannot read `/sys/class/dmi/id/product_uuid`. However, programs such as Consul are relying on it to get fixed IDs, instead they have a different ID on each boot. We propose to use `/etc/machine-id` as fallback https://www.freedesktop.org/software/systemd/man/machine-id.html In order to fix this, this patch does the following: - if `/sys/class/dmi/id/product_uuid` can be read, use it for HostID - else if `/etc/machine-id` exists and has 32 chars, use it and add '-' to have the same format as product_uuid - finally, if notthing works, use the `kernel.random.boot_id` This will greatly increase the number of programs having correct behaviour when those rely on having a fixed HostID. This will fix the following issues: - https://github.com/shirou/gopsutil/issues/350 - https://github.com/hashicorp/consul/issues/4741 |
