Thanks Lonnie, I understand now. -----Original Message----- From: Lonnie Abelbeck [mailto:[email protected]] Sent: April-14-14 4:09 PM To: AstLinux Users Mailing List Subject: Re: [Astlinux-users] Astlinux device inoperable because network interface renamed to eth0 to ethX
Hi Martin, Yes, this is expected behavior for udev to make the NIC ordering 'stickey' to the MAC address. We have a wiki help page related to that: Changing Network Hardware http://doc.astlinux.org/userdoc:tt_change_net_hardware As long as the NIC hardware does not change relative to the flash storage, there should never be an issue. If the flash storage is ever moved to different hardware, you should remove the 70-persistent-net.rules file before making the move. This has never been a issue in production AFAIF and serves a good function to make sure the NIC ordering is consistent. While it would be possible to create an executable shell script "/mnt/kd/rc.local.stop" that removed the 70-persistent-net.rules file on shutdowns, I would not recommend that.
