Title:
systemctl daemon-reload makes systemd crash
Status in systemd package in Ubuntu:
Invalid
Status in systemd source package in Jammy:
New
Bug description:
During the last months systemd has dumped core on two systems with Ubuntu
22.04.
This time it was triggered by "systemctl daemon-reload".
As you probably may know the only thing to do to resolve a system
crash is to reboot the server which is *very* disturbing for our
services.
