[j-nsp] mirror-flash-on-disk

[Markus]

Hi list,

I have a M7i with CF and HDD. Do I understand correctly that if I want 
to keep my configuration between CF and HDD synchronous, I have to run 
"request system snapshot" every time I made a configuration change?

And mirror-flash-on-disk keeps the config between CF and HDD 
automatically synchronous (copies it from CF to HDD), is that right?

If I never do "request system snapshot" and do not enable 
mirror-flash-on-disk and one day my CF dies and the router reboots from 
HDD, it will probably have a very old config, correct?

Thank you!
Markus
