Comment (by gk):

 Replying to [comment:8 mcs]:
 > The difference is really 1A4 vs. 1B0 (0644 vs. 0660).  So we probably
 just need to set the umask before running the make_incremental_update.sh
 script.  Or we could avoid these kinds of issues by generating the
 incremental MARs inside a VM.

 Let's try setting `umask` directly before generating incremental MARs.
 Doing that inside a VM, too, might be a bit cumbersome given our current
 build process (there need to be e.g. builds from the alpha series copied
 around in order to generate the incremental MAR files for the stable
 series and vice versa etc.).
