[Arch Linux] It looks like journalctl --user-unit=... is dropping log lines that happen immediately before a user job exits. Note that I was only able to repro this with user jobs; system jobs don't seem to have this problem.
I create ~/.config/systemd/user/test.service with the following:
[Service]
ExecStart=/usr/bin/bash -c "echo before sleep; sleep 0.1; echo after sleep"
In one terminal I run journalctl --user-unit=test.service --follow. In another terminal, I run (a bunch of times) systemctl --user start test.service.
EXPECTED: I should see both before sleep and after sleep in the output of journalctl.
ACTUAL: I only see before sleep.
Here's what shows up in the -o verbose logs:
