From the gnome_startup_twm attachment:
I've deleted the first 2000+ lines, and I suppose it is entirely
possible that ALL of the Interrupted system calls are related to you
killing the whole thing. But in the absence of anything else to go
on:

But whatever it is, it looks as if *something*, perhaps related to
that EPERM, got logged in a journal. Maybe it only says that things
got killed.
I know almost nothing about current systemd, but is it possible this
got logged differently, i.e. maybe it needs some different magic
words when you use journalctl or whatever it is called (and by this
stage I suspect the words will be blue :)
