That's very suspicious. Hrmmm ....

... a few days ago you proposed

My proposal about -dev does not produce a Joliet tree yet.
If your original ISO was made with -joliet "on", then please
repeat the experiment with Joliet production

   dd if=/dev/sr0 bs=2048 of=gentoo-201501-1.3.8.iso
   xorriso -for_backup -joliet on -dev gentoo-201501-1.3.9.iso \
           -changes_pending yes

Check whether the growth is very near to the estimation
of 105 MB. About everything that's stored between first
session start and first data file of the session should
be re-produced in ithe add-on session. First session starts
at block 0 or block 32, depending on medium type and xorriso
settings.
So not much more than 64 KB of difference would be plausible
here.


Have a nice day :)
