+# Setting a unique hostname to the BMC machine on first boot

+## Problem Description
+In OpenBMC, the hostname discovery is done by the avahi Dbus service at the
+startup. In a network where there are multiple OpenBMC machines, avahi keeps
+getting the hostname conflict and the service name conflict. Hence, the
+problem is to find a solution that resolves these conflicts.
+
+## Background and References
+The detailed issue regarding the hostname and service name conflicts is
+described in the following links.
+
+https://github.com/openbmc/openbmc/issues/1741.

+
+## Requirements
+None.
+
+## Proposed Design
+To solve this, we are proposing a service which assigns a unique hostname to
+the BMC and runs on the very first boot. one of the ways to generate the unique
+hostname is to append the Serial Number retrieved from Inventory Manager to the
+existing default hostname.
