Bug#919507: debian-policy: Policy contains no mention of /var/run/reboot-required
Package: debian-policy
Version: 3.9.8.0
Severity: normal
Hi,
Recent systemd security updates (
systemd (232-25+deb9u8) stretch-security; urgency=high,
systemd (232-25+deb9u7) stretch-security; urgency=high)
require a system reboot to take effect, but the
unattended-upgrades did not tell the user to reboot
(or auto-reboot).
Apparently /var/run/reboot-required is touched to by
debian packages to provide notification when an update
of the package requires a system reboot to take effect.
https://sources.debian.org/src/unattended-upgrades/1.9/unattended-upgrade/#L83
"The Internet" says that it is the postinst script which
is supposed to touch /var/run/reboot-required when a reboot
is required.
If Debian supports user notification when reboot is required
(or automatic rebooting) after automatic upgrade then there
should be some consistent standard. And that standard
should be documented. Someplace.
I don't suppose that there are many packages which require
a reboot to take effect after update, but they are the
important packages. The kernel and libc6 packages
trigger reboot notification, but systemd does not.
I don't see anything in either debian-policy or
the new maintainers guide. (I'm looking at the versions
on debian.net, which I presume are up-to-date.)
Regards,
Karl
