A further gotcha: if you change things in /permanent:
often after the next reboot the most recently written 
file ends up being empty (even if you sync).  This is 
problem with way the OS writes to the flash, I think,
but honestly I don't understand why it happens.

I've avoided this in an embarrasingly hackish way (after 
I write /etc/permanent/x.conf I immediately do a 
"cp /permanent/etc/x.conf /permanent/etc/garbage" so that 
the victim of the bug is the garbage file).
