Comment 2 for bug 1302772

When the upgrade got to here:

Configuration file '/etc/maas/pserv.yaml'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ? Your options are:
    Y or I : install the package maintainer's version
    N or O : keep your currently-installed version
      D : show the differences between the versions
      Z : start a shell to examine the situation
 The default action is to keep your current version.
*** pserv.yaml (Y/I/N/O/D/Z) [default=N] ?

Did you respond with an N (or equivalent) ?
