Never having used Emdebian, I can only give some Debian answers and they'll hopefully be usable. For filesystem UUIDs, I wouldn't use "GRUB_DISABLE_LINUX_UUID="true"". I'd change the new flash card's UUIDs with tune2fs and mkswap to match the copied/cloned "/etc/fstab". For NIC MAC addresses, you have to delete "/etc/udev/rules.d/70-persistent-net.rules" and it'll be recreated with a reboot or with "echo add > /sys/class/net/eth0/uevent". If your original has a fixed IP address, ... You can also change the hostname but you don't need to do so. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
