[erlang-questions] deb package from erlang app release

I've looked at the errors and I think it's because of putting files in the wrong 
place, like you said.
I thought of two ways to package an erlang release as deb:
1. Break the release to several folders as recommended by debian.
Practically copy the official erlang package structure.
2. Make my deb depend on the erlang deb.
In my deb copy only the required erlang apps to /usr/lib/erlang/lib
Copy the app boot file.

In both cases the folders in app start script should be updated.
I'm not sure if 1. will work and I can naively break the release to several 
folders.

Anyone has a sane way to create a deb that follows the debian policy?

I use /usr/lib/myapp for static beam files etc, and /var/lib/myapp for variable 
state information like mnesia databases etc.

Run lintian manually and use "--info" as command line parameter. Then each error 
will be explained.

I suppose it's for Microsoft's operating systems. There is no need to install 
them I guess.

If you need to install your own copy of beam it needs to be linked against the 
system libraries, otherwise you will face problems if for example security 
vulnerabilities are found in the embedded libraries.

Refer to "lintian --info"E: myapp: dir-or-file-in-opt opt/myapp/
> E: myapp: dir-or-file-in-opt opt/myapp/bin/

Consider using /usr/lib/myapp instead.
