Hi, this seems extremely similar to what I am targeting!

I assume you run these hook scripts each time you boot then?  This seems 
like a good idea, I had been thinking about putting that on the writable 
partition and dreaming up some way to ensure that the scripts were only 
run once - I think your design is cleaner (although need to watch boot 
speeds)

I would be very interested to pick over your implementation details if 
you were willing to share (offlist if you don't think it's sensible to 
post publically?).  I'm quite interested in how you picked the package 
list and ordered them and exactly how you implemented the hook scripts 
and failure conditions?

That's really good to hear!  I am currently only planning about 3-4 
packages, but based on what you say I might look to split my packages 
more granually...

Thanks for sharing
