This is *one* possibility. I'd prefer something like preprocessor
"#define"s like for instance CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER.

By using the preprocessor macro approach, you'd keep the information
where it belongs (IMO): It is a property of the *application* whether
IMFS is *needed* or not. It should not be the decision of the operating
system whether to *offer* IMFS or not.

I thought the RTEMS approach is to offer everything to the user but
only pull in (more or less) what is actually needed by the user.
However, there seem to be some hidden (and probably unnecessary)
dependencies which force IMFS into every application.
