Failed to copy resolv.conf, error=1

When trying to remaster an Ubuntu Studio 12.04.2 i386 ISO image in a virtual machine running Ubuntu 12.04.2 i386, I get the following error:

In mount_pseudofilesystems(), /run is bind mounted to /home/vmuser/tmp/remaster-root/run before copying; on both host and remastered systems, /etc/resolv.conf is a symlink to "../run/resolvconf/resolv.conf", so source and destination paths end up pointing to the same file.

Looks like I'm the millionth person reporting this. Launchpad's duplicate bug detection didn't quite help, sorry about that.

Marking this issue as a duplicate of #1011191.

Check to see if /etc/resolv.conf actually exists.
If it doesn't, just "sudo touch /etc/resolv.conf"

Respectfully,
