On two consecutive MKREPRO builds I have the following puzzling diff:

Ignoring /etc/release for now, there are a couple of files in /etc/mtree
where the size is zero in one of the two builds (with corresponding sha256)
and non-zero in the other. Both builds have zero-sized files though,
just different ones.

>How-To-Repeat:
./build.sh -V MKREPRO=yes ...
>Fix:
Yes, please.
