>Description:
/usr/share/info/dir is not reproducible.  After running two reproducible builds, the two /usr/share/info/dir files differed as follows:

Neither of the two was identical to the one in the official 10.0 sets (that again was smaller than both of mine).
>How-To-Repeat:
check out (or unpack) a 10.0 release source tree, then:

./build.sh -u -U -O ../out -m amd64 -V MKREPRO=yes -V MKREPRO_TIMESTAMP=1711614813 -j 16 tools release
./build.sh -u -U -O ../out2 -m amd64 -V MKREPRO=yes -V MKREPRO_TIMESTAMP=1711614813 -j 16 tools release
diff ../out/destdir.amd64/usr/share/info/dir ../out2/destdir.amd64/usr/share/info/dir
