[cisco-voip] CCM6 or 7 recovery disk myth

[Wes Sisk]

To clarify,

the recovery disk primarily contains a basic kernel and fsck.  A little 
digging on linux shows the reason: you cannot run fsck against a mounted 
volume.  Well, you can because linux allows you to do most anything, but 
it usually corrupts the partition even further.  So the recovery disk is 
basically a small livecd that boots a linux kernel and runs fsck against 
partitions on the hard disk.

AFAIK the recovery disk does not contain any RPMs, scripts, or other 
binaries that would be copied from the recovery disk to the hard disk.
