+Subject: [PATCH] fix: Make hotplug socket writable only by root (#25)
+
+The 'hook-hotplug-cmd' was writable by all users, allowing any user
+to trigger the hotplug hook script. This script should only be run
+by root via a udev trigger.
+
+Also move socket into 'share' directory and update references
+accordingly. Since the 'share' directory is only readable by root,
+this adds another layer of security while also being in a consistent
+location with the other sockets used by cloud-init.
