As far as whether or not it should be _mandatory_, to be able to pull
out the version information from an arbitrary bzImage file, can folks
agree that it would at least be a nice-to-have feature? Sometimes
when you're out in the field you don't know what you're faced with,
especially if you're dealing with a customer who likes to build their
own kernels, and who might not have, ah, a very well defined release
process. Sure, you can _call_ them incompetent, and it might even be
true, but wouldn't be nice if there was an easy way to look at a
bzImage file and be able to tell what kernel version it was built
from?
There is a documented procedure for doing exactly that.
See Documentation/i386/boot.txt for details; there is a pointer in the
header which points to a cleartext string, even if the kernel is compressed.
