[erlang-questions] how can I make mnesia/sasl keep quiet

[Jon Watte]

I think that, as long as you call application:set_env(A,K,V) before you
start the application A, you're probably safe. However, for some
applications, this may be hard to accomplish. For example, if you use -boot
start_sasl, then sasl will have started by the time you get to the
interactive prompt.
Maybe building your own boot script that configures this would be a suitable
alternative? That would also work for non-interactive nodes (auto-start in
/etc/init.d, etc)

Sincerely,

Jw
