Agreed.

Is this¹ new with stretch? My linux-images upgrade just like any other
package; here's the penultimate occasion for jessie:

Start-Date: 2017-03-08  19:20:34
Commandline: apt-get upgrade
Upgrade: linux-source-3.16:i386 (3.16.39-1+deb8u1, 3.16.39-1+deb8u2), linux-headers-3.16.0-4-586:i386 (3.16.39-1+deb8u1, 3.16.39-1+deb8u2), linux-image-3.16.0-4-586:i386 (3.16.39-1+deb8u1, 3.16.39-1+deb8u2), linux-libc-dev:i386 (3.16.39-1+deb8u1, 3.16.39-1+deb8u2), linux-compiler-gcc-4.8-x86:i386 (3.16.39-1+deb8u1, 3.16.39-1+deb8u2), linux-headers-3.16.0-4-common:i386 (3.16.39-1+deb8u1, 3.16.39-1+deb8u2)
End-Date: 2017-03-08  19:22:50

(The last one's log was rather larger.)

Same question. My wheezy system has had at least 28 linux-image
upgrades (3.2.57-3+deb7u2→3.2.60-1+deb7u1 to 3.2.86-1→3.2.88-1)
but there's still only one kernel image on the system:

-rw-r--r-- 1 root root  134839 Apr 27 16:52 config-3.2.0-4-686-pae
drwxr-xr-x 3 root root   12288 Apr 28 07:44 grub
-rw-r--r-- 1 root root 2672854 Apr 28 07:44 initrd.img-3.2.0-4-686-pae
-rw-r--r-- 1 root root 1674268 Apr 27 16:52 System.map-3.2.0-4-686-pae
-rw-r--r-- 1 root root 2709184 Apr 27 16:51 vmlinuz-3.2.0-4-686-pae

(I have to notice these upgrades myself because they overwrite
my edited version of /boot/grub/grub.cfg which I then replace.)

Cheers,
David.

¹ I'm not disagreeing that something is holding back the upgrade
on this specific occasion, but this is unusual.
