In case of bug report: Unexpected behaviour you saw

When receiving a particularly large error message, systemd[1] crashes in xsprintf, leaving the system in a state that even rebooting cleanly is impossible.

In case of bug report: Steps to reproduce the problem

call systemd-run with a command that will generate a particularly large error message, in my particulary case saltstack calls systemd-run with apt-get to install packages, one of those packages doesn't exist and apt returns an error message longer than MAX_LINE.
