Switch to new subtemplate .../etc/network/interface.d/* generated two loopback interfaces if the old template was modified

+++ This bug was initially created as a clone of Bug #26058 +++ /etc/network/interfaces wird derzeit von einem relativ starren Template verwaltet, was es nur erlaubt Interfaces zu definieren, deren Name mit "eth" beginnt. Das reicht nicht. * Bug #23947, Bug #23514, Bug #22670: Bridges heißen normalerweise brX * Bug #23411, Bug #19460: Bonding-Interfaces heißen normalerweise bondX * Bug #22967: Unterstützung für VLAN-Interfaces, je nach Modus u.a. vlanX * dummyX, wlanX, ...-Interfaces Gerade in Verbindung mit Virtualisierung und HA sind solche Konfigurationen heute öfters notwendig und sollten abbildbar sein, ohne das man das Template anfassen muß. Die angehängte Version implementiert keine spezielle Unterstützung für die obigen 3 Hauptfällt, sondern vergößert die Flexibilität, so daß sich diese dann auch den bereits vorhandenen "options/"-Mechanismus abbilden lassen. [...] At this bug the old template /etc/univention/templates/files/etc/network/interfaces was splitted to two subtemplates ../interfaces.d/00-base and 10-default The Bug wanted to keep user modifications at "/etc/univention/templates/files/etc/network/interfaces" by moving (and overwriting) the old modified template to "10-default" (debian/univention-base-files.preinst): dpkg-maintscript-helper mv_conffile /etc/univention/templates/files/etc/network/interfaces /etc/univention/templates/files/etc/network/interfaces.d/10-default 2.0.2-1~ -- "$@" As the new subtemplate "/etc/univention/templates/files/etc/network/interfaces.d00-base" has a hardcoded definiton of the loopback interface as well as the old template "/etc/univention/templates/files/etc/network/interfaces", the newly generated conffile gets two looback interfaces. To me this looks like a generic design bug as this mechanism will always lead to a misconfigured conffile. It should be fixed in UCS 3.2 and then backported to ucs 3.1-0/3.1-1 to avoid corrupt updates.
3.1.1: r43423 | Bug #32297: Comment out 'loopback' interface from moved template univention-base-files_2.0.15-1.139.201308232031 3.2-0: r43426 | Bug #32297: Comment out 'loopback' interface from moved template univention-base-files_3.0.2-1.138.201308232031 In the postinst, interfaces/restart/auto is temporarily disabled before the offending lines from the moved template /etc/univention/templates/files/etc/network/interfaces.d/10-default are commented out. /etc/network/interfaces is then committed before interfaces/restart/auto is restored to its original value. Please note, that during the installation of univention-base-files "ifup" and "ifdown" are invoked on the broken file and output some error message. In my tests this is expected and harmless. r43425 | Bug #32297: Comment out 'loopback' interface from moved template branches/ucs-3.1/ucs-3.1-1/doc/errata/2013-08-23-univention-base-files.yaml
