I am concerned with boot time, but don't believe it is image size that 
ramps it up.

Yes, a smaller system which is easier to check, build and maintain. In 
my office I am the leading driver for using linux in a team of 3 (two 
software, one fpga developer) so the less time I spend building, 
rebuilding and checking features I don't need, to ensure they don't 
comprimise the stability of the system, the more faith they have in the 
system I'm putting forward.
