[RS] yes, correct, i describe it in a very short way

[RS] Do i have to run autoremove regulary? To remove old kernels?

[RS] if a new kernel is to setting up, the scripts from /etc/kernel/postinst.d/ are noted:
Setting up linux-image-4.19.0-14-amd64 (4.19.171-2) ...
...
/etc/kernel/postinst.d/initramfs-tools:
update-initramfs: Generating /boot/initrd.img-4.19.0-14-amd64
...
/etc/kernel/postinst.d/zz-update-grub:
Generating grub configuration file ...

So i expected to see there a note for /etc/kernel/postinst.d/apt-auto-removal
