[j-nsp] M7i Compact Flash

[David Ball]

  Well, PSN-2007-08-031 is pretty clear about the compact flash requirements:

"Beginning with JUNOS 9.0 (scheduled for release in February, 2008), a
256MB compact flash device is not large enough to support JUNOS
software installation on M-Series, T-Series, and TX-matrix routing
platforms."

  That said, you seem to have debunked that idea a little.  I'll be
running it by my account team, but I'm expecting a 'maybe it will run,
but it isn't supported' kind of answer.
