[ <time>] systemd: Listening on Journal Socket
What is systemd supposed to be doing?
What other software is involved?
(I may have caused the problem by inadvertedly uninstalling some packages)
How to debug / to recover?
Some more details are at https://unix.stackexchange.com/questions/410812
Thanks in advance for any clue
