Ubuntu16にはserviceA
というサービス名がありますが、同時にデーモンでもあります。
したがって、systemctl daemon-reload
を実行すると、systemctl restart serviceA
のアクションが含まれますか?
man systemctl
から(おそらく世界で最も長いmanページ):
Manager Lifecycle Commands
daemon-reload
Reload the systemd manager configuration. This will rerun all generators (see
systemd.generator(7)), reload all unit files, and recreate the entire
dependency tree. While the daemon is being reloaded, all sockets systemd
listens on behalf of user configuration will stay accessible.
This command should not be confused with the reload command.

Unit Commands
reload PATTERN...
Asks all units listed on the command line to reload their configuration. Note
that this will reload the service-specific configuration, not the unit
configuration file of systemd. If you want systemd to reload the configuration
file of a unit, use the daemon-reload command. In other words: for the example
case of Apache, this will reload Apache's httpd.conf in the web server, not
the Apache.service systemd unit file.
This command should not be confused with the daemon-reload command.
restart PATTERN...
Restart one or more units specified on the command line. If the units are not
running yet, they will be started.
