Bug Description
[Impact]
There's likely a fair number of custom services out there that are similar in nature to cloud-init, unattended-upgrade and the likes. Rather than forcing every user to track down and debug this issue, needrestart should instead have some sort of "self-preservation instinct" and exclude itself from the default restart list.
While this issue isn't particularly new, it has become much more urgent in Noble onwards as we've modified it to default to silently restarting services.
[Test plan]
The fix also includes an autopkgtest for that very issue.
In addition, to test this, one can do in a fresh container with the updated needrestart installed:
# THIS WILL REINSTALL libc6 ON A LOOP ON BUGGY SYSTEMS!!!
sudo systemd-run -u no-self-restart sh -c 'set -e; apt update; apt reinstall -y libc6; sleep 5; touch /tmp/did-
If the bug is fixed, you should find /tmp/did-
[Regression potential]
The most likely regression would be some crash due to some obscure Perl idiosyncrasy.
