Hi Andy,

thanks for your helpful response.

On my Debian Bullseye machine, where I got also a new kernel, I see this:

	# grep -l reboot-required /var/lib/dpkg/info/*
	/var/lib/dpkg/info/dbus.postinst
	/var/lib/dpkg/info/evolution-data-server.postinst
	/var/lib/dpkg/info/gnome-shell.postinst

→ no kernel package.

But on this machine the content of reboot-required.pkgs is today (after I got a new kernel):

	# cat /var/run/reboot-required.pkgs 
	linux-image-5.10.0-28-amd64

So I doubt, that the file is only (!) created by /var/lib/dpkg/info/*, as the grep lacks of this output: linux-image.postinst

Agreed.

Yes! This was a good pointer. Indeed the unattended-upgrades was installed on my Bullseye host, but not on my Bookworm host.

I'm not searching for kind of notifier, instead I want to lookup the reboot by my own (shell) script, like via existance of a file.

I'll install unattended-upgrades now, and will see, if it helps at next kernel installation.

Thanks for your help. Great job.

Best regards,
	Klaus.
