How To Modify the heatseekos.img image

Howto

first off, you need a linux machine and must be uid 1000, usually this is the first user created on the system. 
to find out your id, run this command: `id`

Then find a free loop device:
```
sudo losetup -f
```
usually that will return `loop0` but if not, use whatever it returns in the place of `loop0` in the commands below.

next, load the image into the loop device and mount it.
```
sudo losetup /dev/loop0 ~/heatseekos.img
sudo mount /dev/loop0p2 /mnt
```
next, edit the files to your hearts content in the /mnt directory of your linux machine.
finally unmount the image to save it:
```
sudo umount /mnt
sudo losetup -d /dev/loop0
```

to flash this new image to an sd card, first find out the device name of the sdcard. `/dev/disk3` or `/dev/sdb` etc.
```
sudo dd bs=4M if=./heatseekos.img of=/dev/sdb
```
for a progress meter, use `pv` aquired by: `sudo apt-get install -y pv`
```
sudo -s 
dd bd=4M if=./heatseekos.img | pv | dd of=/dev/sdb
```
