Public bug reported:
After replacing my network card (actually mounting the hardrive into a
different system but the issue is the same) there is no networking
anymore.
There is /etc/udev/rules.d/70-persistent-net.rules which lists the old
MAC as eth0 and prevents the new card from becoming eth0.
There is /etc/network interfaces that lists all the eth intefaces
generated so far (up to eth1) as "iface ethx inet dhcp".
However, the auto line only says "auto eth0 lo".
I am running Gutsy upgraded all the way from something really ancient.
Description: Ubuntu gutsy (development branch)
Release: 7.10
It looks like the system is not completely up to date yet so I will try
to upgrade to the latest packages.
Scenarios that break this way and used to work before persistent net
rules existed:
- replacing your nic (or mainboard in case of onboard nic) when it dies or
when you want a faster one
- putting the hardrive into a different system or making a "mobile"
installation on an USB stick or the like
