I wished to try, purely by experimentation and some googling, to create a vmlinux from my vmlinuz, so as to speed up the initial linux loading.  I am not sure what can be gained, but for waking up from hibernation, I thought it might be useful to cut a few seconds, if at all possible.   Any comments?

I keep seeing from Google searches,  that I can look for the following hex in vmlinuz and then decompress what follows using the following command, plus some other io to extract the compressed portion of vmlinuz.

od -A d -t x1 vmlinuz | grep '1f 8b 08'

But I can't find that signature in my vmlinuz.

Has that signature  changed or am I off track?
