Title:
  ifup calling dhclient when /etc/network/interfaces specifies static IP

Status in “ifupdown” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: ifupdown

  Upgraded Kubuntu desktop system to Karmic, KDE3.5 Remix.  Network
  Manager not installed, using one static IP address:

  $ cat /etc/network/interfaces
  auto lo
  iface lo inet loopback

  
  auto eth1
  iface eth1 inet static
  address 192.168.0.10
  netmask 255.255.255.0
  gateway 192.168.0.1

  and ifupdown version: 0.6.8ubuntu21

  Problem is, on boot _and on starting a desktop session_  the system pulls a dynamic IP using dhclient.  Running "sudo ifdown eth1", then "sudo ifup eth1" sets the IP back to .10, but dhclient then starts, and pulls a dynamic IP from the router, and exits - no leftover dhclient sitting in the process table ("ps ax | grep dh"  finds nothing.).  I know it's not a network manager problem, since that package isn't on the system, and neither is zeroconf - the ultimate workaround was to move all the dhclient executables to /sbin/dhcp - now "sudo ifup eth1" sets the .10 address and it stays put.  I noticed bug 446031, which may be related, but the version of ifupdown which is stated there as the "fix" isn't being loaded when I update the system, so I'm not sure how to get that version and test it here.
  (Anyway, /var/run/network is present on this system, so I'm not sure it's the same bug.)
