A typical cases to do this is when you don't want to reinitialize 
everytime, particular if the data is on a slow bus like i2c, etc and you 
are writing a time-constrainted system. In which case, reading from 
flash or loading of initrd (finding offset, uncompressing, loading as 
fs, etc) are equally bad.
