** Description changed: + [impact] + + during systemctl daemon-reload, systemd sometimes segfaults while + serializing a service. + + [test case] + + problem is intermittent, but the upstream bug suggests a reproducer. + Also see original description. + + [regression potential] + + this adjusts serialization, so any regression would likely occur during + serialization/deserialization, e.g. at daemon-reload. + + [scope] + + This is needed for Bionic and later. + + this was introduced by commit e266c068b5597e18b2299f9c9d3ee6cf04198c41 + which is included starting in v234. The commit to fix it is + e9da62b18af647bfa73807e1c7fc3bfa4bb4b2ac which is not yet included in + any release. + + The PR to fix this is https://github.com/systemd/systemd/pull/15546 + + [other info] + + there is an additional PR that further avoids the error, but has not yet been accepted, and may not be accepted as it may not be necessary. + https://github.com/systemd/systemd/pull/15370 + + [original description] + Proximate syslog: Apr 18 16:26:56 gate2 rssmonitor.py[2001]: settings: Running: ip -all netns del Apr 18 16:26:56 gate2 systemd[1]: /lib/systemd/system/dbus.socket:4: ListenStream= references a path below legacy directory /var/run/, updating /var/run/dbus/system_bus_socket → /r un/dbus/system_bus_socket; please update the unit file accordingly.
