Simple. Vendor would only need to ship a single image to support
all possible OS name overrides. CD space is precious, and with SMP,
highmem, P4/K7 optimised, preempt and a number of other such options, the number
of kernel combinations grows and grows.  Having a set of images compiled
saying "NT" and another set saying "95" and another set saying "Linux"
triples the numbers of kernels needed to be shipped, and hence, is
undesired.

Clearer?
