OS X Lion Installer DRM?

Is there DRM in InstallESD.dmg disk image from OS X Lion Download? Are you required to enter an Apple ID upon install to validate it? Page 2 of this Arstechnica OS X Lion review:

Mac OS X, Lion has no serial number, no product activation, and no DRM of any kind. In fact, the Mac App Store’s licensing policy is even more permissive than past releases of Mac OS X.
