The script seems to have disappeared in more recent iterations, and 
seems to have been explicitly removed.

   $ ls -1 /etc/postinstall/0p*
   /etc/postinstall/0p_000_autorebase.dash
   /etc/postinstall/0p_update-info-dir.dash

Was that a deliberate change?  Not complaining here, just asking, so I 
know to recreate resolv.conf if/when my delegated IPv6 prefix changes.

Thanks
