DHCP lease fails at startup after upgrade of ifupdown (10.04)

[martijn.list]

Hi,

I have Ubuntu 10.04 running on VMware ESX. After upgrading ifupdown (to
0.6.8ubuntu29.2) dhclient no longer seems to acquire a DHCP lease. If I
restart the network manually, dhclient is able to get a valid DHCP lease.

If I revert back to the previous version of ifupdown (0.6.8ubuntu29)
dhclient is able to get a DHCP lease. I have been able to replicate this
on two different installations of 10.04 on VMware.

Kernel:

Linux ubuntu1004 2.6.32-27-generic-pae #49-Ubuntu SMP Thu Dec 2 00:07:52
UTC 2010 i686 GNU/Linux

Any idea why the updated ifupdown fails to get a DHCP lease at startup?

Kind regards,

Martijn Brinkers
