Comment (by skyblaster):
After backing up the caldata_backup partition, I went ahead and built and
loaded 14.07 using ImageBuilder and the mtdlayout modification above.
Here is the output of dmesg on boot:
{{{

I could be wrong, but to me it looks like the caldata_backup partition was
overwritten and a new one was created at the end.
