Hi Chris! Good question and no, booting in single-user mode and running fsck -fy did not fix the problem until after I fixed the permissions on the sudoers file manually. I don't know why this might be and someone might stand up and tell me it can't be, but that was my experience this morning. In fact, I did repair my permissions with the Disk Utility GUI, but only after manually fixing the sudoers file in single-user mode.

Thanks for the thought though!

I'm glad the single-user-mode fix worked. Before that, you were in a rare catch-22. To repair permissions on /etc/sudoers, you needed to be root. But to become root, the system needed to read /etc/ sudoers. So the Disk Utility's Repair Permissions feature would not have helped, because it needs root access to function.

Other solutions that would have worked are to boot from alternate media (either a CD or a Firewire drive), or to boot the machine in target disk mode and repair the permissions via another Mac.
