Lintian tag: systemd-service-file-shutdown-problems

Type: warning

Description (from lintian-explain-tags)

The specified systemd .service file contains both DefaultDependencies=no
and Conflicts=shutdown.target directives without Before=shutdown.target.

This can lead to problems during shutdown because the service may linger
until the very end of shutdown sequence as nothing requests to stop it
before (due to DefaultDependencies=no).

There is race condition between stopping units and systemd getting a
request to exit the main loop, so it may proceed with shutdown before all
pending stop jobs have been processed.

Please add Before=shutdown.target.

Please refer to https://github.com/systemd/systemd/issues/11821 for
details.
