After a lot of googling I did succeed in getting wget out of the fsimage.qcow2 file by installing qemu and nbd-client + following this guide:
http://blog.loftninjas.org/2008/10/2...u-disk-images/
I had to leave the command:
#sudo qemu-nbd fsimage.qcow2
running in one terminal window and accessing the image from another window after issuing:
#nbd-client localhost 1024 /dev/nbd0
and then mounting with:
#mount /dev/nbd0p1 /mnt
But how can I make the new wget command overlay the older one? Where do I put it on the PB902?
