are there more than 10 lines of logs for the current /instance/ of the
unit? E.g. has it produced more than 10 lines of output since it was
started?

For example, I launch a lxd container of xenial, and $ systemctl status
-n 20 cloud-init -> displays 20 lines of logs.

How long is the journal for that unit since boot? E.g. journalctl -b -u
SERVICE | wc ?

Title:
  systemctl -n option ignores values greater than 10

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  The manpage for systemctl says that -n can be used to specify how many
  journal lines to show.

  It only works for values <= 10, there is no way to make it show more
  than 10 lines. For example 'systemctl -n 100 status SERVICE' shows 10
  lines, not 100. 'journalctl -n 100 -u SERVICE' does work as expected
  though.

  Its confusing if you are not aware of this and can make you miss
  important output from a failed program.

  systemd package version: 229-4ubuntu17
  systemctl version: systemd 229
