If you're testing with multiple images/devices that have the same IP
address / hostname then it can be annoying to deal with host key
mismatches all of the time. As a MITM attack is unlikely in the local
test environment, provide a command line option to pass the appropriate
options to scp/ssh to disable the host key checking.
Note: if you wish to apply this permanently, the best way is to do it
through your ssh configuration e.g. by adding the following to your
~/.ssh/config:
Host 192.168.7.2
UserKnownHostsFile=/dev/null
StrictHostKeyChecking no
