[arm-allstar] any sneaky ways to set idrecording

[Doug Crompton]

Lowell,

 First of all yes there is a notlelemtx. I don't believe there are any
commands in Acid that are not in our code. However the opposite is not true.

As for dynamic control of config parameters. That can and probably will be
done in many cases in the future in improvements we make in the code. It
has already been done in simple-usb-tune-menu where parameters in a running
system are changed on the fly.

Things like id-recording can be changed now simply by changing the file it
points to. Copy a different ID to the file using a script. You could also
use the tailmessage command in a similar way dynamically changing the
tailmessage files.
