EDIT: FIXED. Current version is 0.7 (Changelog: line 13 had a hardcode for sda2 and line 10 wasn't copying correctly so I split it)
Yeah the first line of the script lets you easily change the location of the SD card. Well the physical location of the partitions is usually very handy but in this case you need the mount point. Something like changing sdhc="/media/mmc1" to sdhc="/media/mmc2" would do the trick.
Don't worry finding the mountpoint is easy.
$ partmount() { df -h | grep /dev/$1 | awk '{ print $6}'; }
$ partmount mmcblk1p1
The output is the mount point for your microsd card. It should be /media/mmc2 or thereabouts.
Or you could just use the modified script (defaults to wherever /dev/mmcblk1p1 is mounted but prompts anyway, you can just hit enter):
#!/bin/bash
