This is a known issue an workaround. It only occurs if the ethernet cable is
plugged in before boot.

As well as your workaround there is a know initscript patch:

https://dev1galaxy.org/viewtopic.php?pid=15493#p15493

It is already reported in Debian, but there is no sign of it being addressed.

We will add the workaround to the Release Notes and consider forking the
package.

Thanks

Mark
