I have a tar of my packages and am basically untaring the file .. the tar
file is in the device so I have a copy of the pkg.tgz in SSD as well as
PCIe and and im untaring it locally..  so source and destination is same
disk.. I have untared it numerous times and got the same result. 

Is there anything setting in netbsd that I forgot to enable.
