Public bug reported:
[ Impact ]
needrestart supports restarting containers with outdated binaries when
running in the context of the hypervisor, however said support appears
to be broken in Noble and Oracular.
While we do not want to handle containers as part of the APT-triggered
restarts, the user might rely on that particular feature in their own
scripts.
This will get fixed by backporting an upstream fix, as well as amending
the Ubuntu-mode patch.
[ Test plan ]
```
apt install -t noble-proposed needrestart
lxc launch ubuntu-daily:noble to-be-restarted
lxc exec to-be-restarted touch /tmp/restart-marker
lxc exec to-be-restarted apt remove needrestart # we don't want it to restart
outdated services from within the container!
lxc exec to-be-restarted apt reinstall libc6 # should make a whole lot of
things outdated.
apt reinstall libc-bin # the actual package doesn't matter, we just want the
needrestart hook in an APT context
sleep 3 # to be sure, wait a bit for any container restart to take effect
lxc exec to-be-restarted stat /tmp/restart-marker # This is SUPPOSED TO WORK,
we don't want the APT hook to touch containers
needrestart -r a
sleep 3 # to make sure any restart has time to take effect
lxc exec to-be-restarted stat /tmp/restart-marker # This is SUPPOSED TO FAIL,
the container should have restarted.
```
[ Where problems could occur ]
While the "Ubuntu mode" code is touched to avoid restarting containers, errors
in that code could lead to
us restarting user containers during unattended-upgrades, hence the relevant
test in the test plan.
