Recommended procedure for cloning Warp v2 SD cards with a external PC.
Insert the SD master and obtain the image:
1 - cd /media/xxxxx
2 - tar -zcvfp /root/ImageName.tar.gz *
Insert the new SD card and commit the image:
3 - unmount /media/yyyyy
4 - mkfs.ext4 /dev/sdb1
5 - tune2fs -i 0 /dev/sdb1 -L WARP-SD
6 - mount the SD card
7 - cd /media/WARP-SD
8 - touch .WARP-SD
Once a SD has been cloned it can be inserted into any Warp v2 and will automatically boot.
