Comment 6 for bug 690873

The sudoers.d/README claims that sudoers isn't a conffile, but it is; also, this README is actually parsed by sudo.

(I recall sudoers being both a conffile AND updated in postinst in the past, but that appears to no longer be the case)

If we move to a sudoers.d file for Ubuntu's %admin entry, then we need to fix upgrades to actually add the #includedir directive as README also claims that it is NOT added on upgrades. (To me, this seems a bad idea: the package adds a helpful sudoers.d facility, but doesn't ensure that it's actually working across upgrades.....)
