This is what I have in /boot and, as stated above, usual outcome of
upgrades, both in Stretch and in Ubuntu 16.04:
-rw-r--r-- 1 root root 186695 Mar 30 03:16 config-4.9.0-2-amd64
-rw-r--r-- 1 root root 186380 May 2 17:21 config-4.9.0-3-amd64
drwxr-xr-x 5 root root 4096 May 19 08:55 grub
-rw-r--r-- 1 root root 19660713 May 17 16:43 initrd.img-4.9.0-2-amd64
-rw-r--r-- 1 root root 19534447 May 18 08:40 initrd.img-4.9.0-3-amd64
-rw-r--r-- 1 root root 3169870 Mar 30 03:16 System.map-4.9.0-2-amd64
-rw-r--r-- 1 root root 3176652 May 2 17:21 System.map-4.9.0-3-amd64
-rw-r--r-- 1 root root 4193832 Mar 30 18:43 vmlinuz-4.9.0-2-amd64
-rw-r--r-- 1 root root 4204320 May 2 17:21 vmlinuz-4.9.0-3-amd64
As you can see, 2 kernels. All i do is my morning routine which consists
of apt-get update && apt-get upgrade, followed by apt-get dist-upgrade
in case of need(as stated before, usually case of need is kernel
upgrade). Of course, it is followed by apt-get autoremove too.I do not
have anything unusual on this system. It was fairly recent install of
jessie(few months ago), followed by upgrade to stretch right after
install. Was installed from unofficial net-install cd with firmware on
it. Also, nothing was changed in apt preferences and stuff like that.

Well, I was always under assumption that in case of grub2 you can change
anything in grub.cfg by editing /etc/default/grub and files in
/etc/grub.d/. Perhaps I was wrong about it, in which case I do
apologise.
