Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Upgrading to 0.8.45, boot would pause for a long time trying to start ntpd

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

either downgrading to 0.8.44 or removing the eth1 entries in /etc/network interfaces

   * What was the outcome of this action?

either of the above actions fixed the long pause issue.

   * What outcome did you expect instead?

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Correction to the original report:

The problem seemed to be with my /etc/network/interfaces file, using

allow-hotplug

instead of

auto

for ethernet interfaces.


   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I edited the /etc/network/interfaces file to better reflect my actual use case,
and the result included below worked as I hoped without delay on start-up.

   * What was the outcome of this action?
   * What outcome did you expect instead?
