I agree.  Rules for read-only access should be more permissive than
those for read-write access.  Rules for bootloader read-only access
should be relaxed even more.

For example, we don't really care about permissions and timestamps.  It
would be nice to get them right, but failure to boot because of a
nanosecond timestamp would be too much.  Likewise, we don't care if some
files are compressed or use a file size representation we don't support
and long as the files we need don't use it.
