Multiple SD cards for multiple OS's?

[pfeerick]

I'm currently using 1 card, and making a back up image via Win32DiskImager each time I switch, and then using it to restore.

That's working for me, since I'm patient. My main angst is having to use 16GB images on a card that's supposedly 32GB (Sandisk Ultra).

If you're running the longsleep ubuntu or debian linux builds, you can resize the file system to use the full 32GB (or whatever size your card is). 

Code:

sudo /usr/local/sbin/resize_rootfs
