Should systemd be running as a sub-process of itself?

I just noticed in System Monitor that systemd is running as pid 1 AND that within that process it is listed as a dependent process of itself, running again under process 1 as pid 933 and with another set of various processes running as dependents of 933. Is this normal or something that indicates a problem?

I think it's probably your `systemd --user` instance - does `systemctl status user@$(id -u).service` report the same PID?

owner of pid1 was root and myusername listed as owner of pid 933

also the respective commandlines: pid1: /sbin/init/ splash pid 933: /lib/systemd/systemd/ --user

Please use the [edit] button to add + format that information into your question. Please run the systemctl --status command as your ordinary `myusername` not as root.

I did that wrong. I'm fixing it now.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
