Persistent net rules

Do the popular Debian based distros for the RPi use Persistent Net Rules?

I put an SD card in a different Pi and it tried to bring up a non-existent eth1 because eth0 was associated with the MAC address of the interface of the other machine.

This could cause much confusion in many situations.

The relevant files in my case were /etc/udev/rules.d/70-persistent-net.rules and /lib/udev/write_net_rules now both deleted.

My application is RASPBX and I don't know how it compares with Raspian, NOOBS etc. in this respect.

Hi,

I had this issue several times on some other distros. The solution was to erasse the dynamically written content of

/etc/udev/rules.d/70-persistent-net.rules

since it is being filled by /lib/udev/write_net_rules according to your hardware. So, it looks which ethx is present and uses only this one, instead of adding the newly found interface.

Best regards,

Markus
