[erlang-questions] Release handler seems to be not starting some applications
Mon Sep 10 22:49:08 CEST 2012
I figured out that it's not important to start sasl, and it's sufficient
just to load it (see the included applications below the started ones).
Just to be sure, tried to make an upgrade that doesn't stop or unload sasl,
and the system still behaves in the same way.
For what it's worth, the occurring error with lager is related to dynamic
code compiling (it's basically a copied mochiglobal module).
Will try to use the latest Erlang, I've been testing this stuff in R14B04.
