No :-(

That looks right.

Yup - that's the effect of "cat -e" - it marks the end of the line.
(So you can spot trailing whitespace)

That would probably break things, yes.
The "-I" flag says  "initialise the specified modules (and no others)".

So  "-I smux" means "initialise SMUX support, but nothing else",
and will therefore turn off *all* the access control settings.

(This probably isn't sensible, and we may need to review how the
"core" agent functionality is handled.   But that's how it works)

The safest approach would probably be to build a minimal agent
(plus SMUX support) - i.e. turning off the unwanted MIBs at
compile time, rather than run-time.
