Starting our services on Ubuntu systems (and Debian?) gives the following log line: > Oct 19 00:06:20 ubuntu1804 bash[2008]: mesg: ttyname failed: Inappropriate ioctl for device This is caused by us starting our services through a login shell (for locale, see bug 5102) and Ubuntu has this in ~root/.profile: > mesg n || true (Note that this is only seen in "systemctl status" as it happens before we set up our own logging)
Tested on Ubuntu 18.04.
