On restart 'Livepatch-Notif' is always a zombie process

[Chris]

As shown here - https://imageshack.com/i/pl753Ekfp AFAICT I don't have
livepatch enabled. Running:

chris at localhost:/var/log$ ps axo stat,ppid,pid,comm | grep -w defunct
Z+    3283  3290 livepatch-notif <defunct>

3283 chris     20   0  585404  23776  17608 S   0.0  0.2   0:00.09

livepatch-notif    

It's no big deal to remove the zombie by killing update-notifier
however I don't know if that's the right thing to do or not and why is
livepatch-notif always a zombie process after a restart?
