Comment:

 The sha256sums.txt verification of the .mar files is going to fail here.
 To avoid repeated re-signging by all of the official builders, we decided
 that both of the sha256sums.txt files will contain shasums of the
 *unsigned* .mar files. So this means that you need to do 'signmar -r'
 (from the mar-tools) on each .mar file before verifying its sha256sum.

 I'm surprised you didn't run into this. Did you test this on a 4.5 build
 or a 4.0 build? We will only use this for 4.5 and later builds, so you
 don't need to worry about supporting the unsigned mar case at this point.
