Yes, because you will surely upgrade the code at some point (new features,
bug fixes) and it's a pain to do this by hand or even using scripts. I
suggest taking a look at some open source Erlang-specific software that
allows you to build and distribute (install) your Erlang applications
relatively painlessly. The builder component is called Sinan (
http://code.google.com/p/sinan/); the distribution/installation component is
called Faxien (http://code.google.com/p/faxien/). I use these for the job
and although there are some minor imperfections, I would never go back to
the "old way".
Also take a look at the Faxien/Sinan cookbook at
http://myfcci.com/yab/2008/09/11/my-faxiensinan-cookbook/ to get started
(disclosure: I wrote the cookbook, but I have no vested interest in Sinan or
Faxien other than using it for my work).
I don't ever anticipate the need for hotswapping of code. The users will

How would they like to upgrade to the latest release just by typing in "$
faxien upgrade-release kevins_stuff" and then restart the app?

No question is ignorant.
Hope this helps.
