journal excerpt

I ran into this while messing with the getty@.service and autovt@.service
units. 

This is what I was doing just before the error:

# cat > /etc/systemd/system/getty@.service <<EOF
.include /usr/lib/systemd/system/getty@.service
[Service]
TTYVTDisallocate=no
EOF
# systemctl daemon-reload

[log in on a new vt]
[log out, notice that the tty still got cleared]

# ln -s getty@.service /etc/systemd/system/autovt@.service
# systemctl daemon-reload

[log in on a new vt]
[log out, notice that agetty does not start again]
[check the journal, notice that systemd[1] has dumped its core]</pre>
