[Bug 1949241] [NEW] unattended-upgrades conflicts with kubernetes gracefullshutdown

[Piotr Maksymiuk]

Public bug reported:

Kubernetes 1.22 brings GracefullNodeShutdown into beta, by leveraging
systemd-inhibit. It tries to detect the current InhibitDelayMaxSec, and
if it's less than the requested, will place a 99-kubelet.conf in
/etc/systemd/logind.conf.d

However, this doesn't work as systemd-analyze cat-config
systemd/logind.conf would show that
/usr/lib/systemd/logind.conf.d/unattended-upgrades-logind-maxdelay.conf
comes last, and overwrites any requested maxium down to 30 seconds.

This file should either be customizable, or renamed to something like
10-unattended-upgrades-logind-maxdelay.conf so that it would be
evaluated earlier

This is on a cloud image of Ubuntu 21.10
