Of course, although perhaps it could.

No signature needs to be added to the boot drive or kernel, just checksums in the bios image. > what tivo actually does is very similar to this > > they encode into the bios the ability to check a checksum/signature for > the kernel+boot filesystem and if they don't match look to see if there is > another kernel+boot filesystem available > > then software on the boot filesystem checks to see if the rest of the > system has been tampered with before it mounts / > > the GPLv3 is trying to do this.
