You missed a point, the update through setup could fail to
start octave. Octave has a very very large list of dll's to load.
I consider it more likely than your case.

I will add a note on README for next octave package,
if I do not find a better solution

At begin, I was thinking something like that, but I dropped it:

- High chance to fail during post install
- problematic behavior during remove
- hard to synchronize
- 1 script only versus more than 50 post-install script
