[f-nsp] Copying software to secondary flash deletes primary flash's content?

[Franz Georg Köhler]

Hello,

I read this, but both images fit onto the management module.

However, I removed the secondary LP image since I thought it is more
valuable to have a secondary management ironware to boot from in
emergency cases than a secondary lp image (which could be downloaded
from tftp anyway, as long as there is still a working ip connectivity).

But now I see that sync-standby seems to switch round-robin-style
between primary and secondary flash, too:

Finally, I wonder why one line card has pri & sec flash populated, while
I cannot populate both flash on card#5?

I think line card#6 has automatically downloaded the software from the
management module while I flashed manually card#5.
