It depends. If your app references only shared assemblies (which will be
in the GAC or in the default location - $prefix/lib, currently), then
doing that is fine. If you have private assemblies, it's better to
install the files in $prefix/share/appname/ and install a wrapper in the
bin dir (note that the wrapper won't need to set MONO_PATH, since the
loader looks in the directory where the binary was found).

I guess lintian needs to be updated to not do that, at least for
CLI files. I'm not sure, though, if requiring binfmt_misc is
appropriate: I would personally alwasy install a wrapper in bin
and the assemblies in lib/appname/ or share/appname/.

This could be done in the postinst, but I think it's best to do it in
two stesps: register an assembly for aot in the postinst if appropriate
(not all the assemblies should be aot compiled). Then the admin would
run a script (which could be called by the postinst too) which compiles
all the assemblies registered in one go (assemblies may need to be
re-aoted whne hw changes happen or when a base assembly is updated etc.).
