Probably you are right. But it makes me wonder why the previous upgrade
(from Wheezy to Jessie), as well as this one (from Jessie to Stretch)
did not upgrade the kernel automatically, as it did with other packages.
Because each time you did not follow the release notes chapter about
upgrading the kernel, and you had not installed a meta-package which
depends on the latest available kernel.
Unlike most packages, a new kernel version is not a new version of an
older kernel package, they are different packages (with different names,
which contain the kernel version). This is why you can have several
kernel versions installed at the same time. Upgrading a kernel package
does not bring a new kernel version.
There are two ways to install a new kernel :
- install it manually ;
- install a kernel meta-package linux-image-<processor-type> without a
specific kernel version in its name which depends on the latest
available kernel package. When upgraded, il will "pull" the new kernel
package by dependency.
The Debian installer installs a kernel meta-package by default now.
