To that end, we will optionally include an '|| true' postfix to each route line allowing users to work with ifup/ifdown without using --force option. We may at somepoint not want to emit this additional postfix, and add a 'strict' flag to this function. When called with strict=True, then we will not append the postfix. 1. http://askubuntu.com/questions/168033/ how-to-set-static-routes-in-ubuntu-server s post-up route adds pre-down route dels || truet gwR R Rp R s 0.0.0.0R s defaults ::R* i s -A inet6 defaults %s %s %sR� s -A inet6s -nets %s/%ss %s %s( R3 ( R� t routet indentR8 R R t or_truet mappingt default_gwt route_linet k( ( s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyt _render_route] s: " "#c C s� g } | j d i � } | j d d � } | rhx�t | � D]$\ } } d } | | d <| d | d <| j d d � | d <d } t | � r� | d 7} n | j d � } | | d <| d d k s� | d d k s� | d d k rd | d <| d k r�| rd n d | d <q�n� | d d k r>d | d <d | d <nk | d d k red | d <d | d <nD t | � r�| d d k r�| d k r�| r�d n d | d <q�n t g | D] } d | d | k ^ q�k r�d | d <n t t | | d | �t | | � t | | | � � } x6 | j d g � D]" } | j | j | d d �� q.W| j | � q= Wny g } d | k s�d | k r�| j d j | � � n | j d j | � � | j t | d d d! d �� | j | � | S(" NRD s accept-raR@ R/ RB R= RZ RA t 6R t dhcp4t dhcp6s ipv6_dhcpv6-statefult dhcpt 1t 0t accept_ras ipv6_dhcpv6-statelesst ipv6_slaacR� s auto %sRC t aliasR` t routesR� s s bond-masters bond-slavess auto {name}s iface {name} {inet} {mode}i RT ( RS t popRw t enumerateR R� R0 Rc R< RY t extendR� R3 R4 ( R� R6 R` t sectionsRD R� R@ R7 RT t subnet_inetR� Rb R� ( ( s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyt _render_iface� sZ ' c s� i d d 6d d 6d d 6i d d 6d d 6g d 6} x; | j � D]- } | j d � d k r@ t j | � } q@ q@ W| j } | r� d j | � | d d d <n | j } | r� d j | � | d d d <n i d d 6d d 6d d 6d d 6d d 6d d 6� g } | j | j | � � x` t | j � d � f d � �D]= } | j d � d k rZq9n | j | j | d | �� q9Wx* | j � D] } | j | j | � � q�Wd j g | D] } d j | � ^ q�� d S( s1 Given state, emit etc/network/interfaces content.R� RC R� R/ RA R� RZ R= RD R+ i R) R( i i RL i RJ i RK i RM R: c s � | d | d f S( NR/ RC ( ( R� ( t order( s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyt <lambda>� s R` s s ( t iter_interfacesRS R^ t deepcopyR) R1 t dns_searchdomainsR� R� R5 t iter_routesR3 R� ( R� t network_stateR` R� R6 Rn t searchdomainsR� R� t s( ( R� s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyt _render_interfaces� s: c C s� t j | | j � } t j t j j | � � | j r@ | j n d } t j | | | j | � � | j r� t j | | j � } t j t j j | � � t j | | j | � � n d S( NRp ( R t target_pathR� t ensure_dirR| R} R� R� t write_fileR� R� t _render_persistent_net( R� R� t templatest targett fpenit headert netrules( ( s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyt render_network_state� s N( t __name__t __module__t __doc__Rw R� R� R� R� R� R� ( ( ( s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyR� R s 2 A /c C sr d } t d i | d 6| d 6d d 6� } | s9 d } n | j d � sU | d 7} n | j | d | �} | | S( Ns etc/network/interfacesR� R� R� R� Rp s R` ( R� Rw t endswithR� ( R� R� R` R� R R� ( ( s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyt network_state_to_eni s c C sw d d d g } d d g } x- | D]% } t j | d | d | �s" t Sq" Wt j | d � } t j j | � ss t St S( Nt ifqueryt ifupt ifdowns /sbins /usr/sbinRm R� s etc/network/interfaces( R t whichR� R� R| R} R� R� ( R� t expectedRm t pt eni( ( s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyt available s ( R^ R~ R| R� Rp R R R� R t cloudinitR t loggingR t getLoggerR� RQ R� R� R� R< RY R� Rc R� R� R� R� R� Rw R� R� ( ( ( s5 /usr/lib/python2.7/site-packages/cloudinit/net/eni.pyt <module> s4 9 � *�
