Thank you all.

On the same subject: if I upgrade some dependencies, I've noted that when I
generate the .appup file with rebar it generates them for every dependency:

ubuntu@REDACTED:rebar generate-appups previous_release=myapp-1.3.6
==> rel (generate-appups)
Generated appup for bear
Generated appup for exometer_core
Generated appup for folsom
Generated appup for goldrush
Generated appup for jiffy
Generated appup for lager
Generated appup for myapp
Generated appup for parse_trans
Generated appup for setup
Appup generation complete

If I follow the steps in https://github.com/rebar/rebar/wiki/Upgrades, will
these dependencies also be hot code updated?
