Do you mount the DOC as Read/Write, Any worries on how many times you can
write to the DOC before you have problems? I am looking into putting the
DOC into the field for 7+ years, rather not run into problems with writes if
I can help it. The current plan is to mount it Read only and mount it
Read/Write only when it need to be updated.
