Comment:

 This file is created by calling dbus-uuidgen.[[BR]]
 Prior to r49300, machine-id was created during post-activate and left in
 ${prefix}/var/lib/dbus/.[[BR]]
 I thought it was better to create machine-id during post-destroot so it
 would be removed if[[BR]]
 ever the user wanted to uninstall dbus.[[BR]]
 I forgot that upgrading would be a problem.

 The solution is to simply remove the old file in
 ${prefix}/var/lib/dbus/.[[BR]]
 Everything should then proceed.

 I will try to add some code to give a better error message.
