osstest's d-i runs take more like 15 minutes.  As I say, this could be
improved by using something like FAI, but by a factor of at most 2 I
think.  Instead of working on that, I have been working on reusing an
install when it is feasible to do so: specifically, after a passing
job and when the host is to be reused by the same flight, with an
identical configuration.  In my tests that saves about 50% of the host
installs.  I haven't yet completed and deployed this.

Ian.
