Hi,

there are packages (dbus, I'm talking about you!) that suggest a reboot
after a package update because they don't feel like being able to be
updated without a reboot.

needrestart should detect that state and report it, otherwise the
suggestion to reboot is gonna be missed by many local admins.

Dbus touches /var/run/reboot-required in that case, and the comments in
dbus' postinst suggest that there are already packages like
unattended-upgrades that use that file to suggest a reboot. Implementing
this in needrestart should be easy enough, I hope.

Thanks for considering this.

Greetings
Marc
