Initial reproducibility check at 6aee6394e64f60f7cf57e2091322b7fc1b86cc98:

Timing should be fixed; filesystem size difference very likely symptom of other issues.

Various base directories/files have varying mtimes (eg. /dev/pts, /etc)

This is generated in ./auto/scripts/apt-snapshots-serials. I think this is a false-positive; ie. someone uploaded something to Debian / snapshots?

This is Bug #15187. Note that this also happens for files outside of /usr/share/fonts (the above is under /usr/local and there are others varying under, say, /usr/share/poppler/cMap/.
