# Provides: bootin
# Short-Description: Boot in whichever multiboot system you got
# Description: If you dont have a keyboard and monitor hooked up on your pi and you want to 
# boot for example from Raspbmc to Raspbian or vice versa using SSH from a remote computer.
# First you need to get the partition numbers for all your systems and put them in the values bellow.
# Do these steps to get them:
# mkdir /tmp/noobs
# sudo mount  /dev/mmcblk0p3 /tmp/noobs
# cat /tmp/noobs/installed_os.json
# Example: 
#  "name" : "Raspbian",
#  "partitions" : [
#"/dev/mmcblk0p5",  <---- 5
#"/dev/mmcblk0p6"
#.....
#  "name" : "RaspBMC",
#  "partitions" : [
#"/dev/mmcblk0p7",  <----- 7
#"/dev/mmcblk0p8"
#...
# the mmcblk0p 5 is important.. Note the 1st number for every /dev pair...these are the numbers you want. These numbers represent your OS systems.
# So in the above example i want 5 and 7. If you have more than 2 systems, just copy paste a new section like the kodi) section I have bellow...
# and change the sed value \1'x' where is x is the value of the other partition. Also put the name you want for that OS, ex pico) and add that extra OS 
# at the bottom with the helper command: "Usage: bootin {kodi|raspbian}"
