extra newlines in logged container output #242
Description
container output, as seen in journald, has random newlines inserted.
Steps to reproduce the issue:
There is probably a simpler way to do this, but this is what I did:
cat > /etc/systemd/system/conmon-test.service
[Unit]
Description=test
[Service]
ExecPre=-podman rm conmon-test
ExecStart=podman run -d --rm --name conmon-test --log-driver journald --entrypoint bash centos -c "find /"
systemctl start conmon-testjournalctl -u conmon-test
Describe the results you received:
Output has random newlines. For example:

The number of newlines seems to vary.. in my actual workload (not this test) I get a half dozen per line of output.
Describe the results you expected:
No inserted newlines.

I've seen the same with podman 2.2.1 on centos too.
