<br>
I have a question: systemd monitors almost everything it seems to me. So I wonder:<br>
Under what conditions is it necessary to issue a daemon-reload, and why can't systemd find out itself that a daemon-reload is required?<br></blockquote><div><br></div><div>There are some cases where systemd can detect the proper time for a daemon-reload, and does it implicitely</div><div>systemd also check mtime of configuration files so it can see when a daemon-reload should be done.</div><div><br></div><div>However it is not because a file has been modified that systemd should decide to reload by itself.</div><div>multiple unit files need to work together to make a working environment, and systemd can't know when all changes are consistent and</div><div>it is safe to reload. So systemd will want an explicit order from the user.</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
So if I think a "manual" daemon-reload is required, is it safe to do it from within a unit?<br></blockquote><div><br></div><div>Usually, calling daemon-reload from a unit is a sign of bad design or misunderstanding of some tool. What exactly is the problem you are</div><div>trying to solve ?</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
I have a "generator-like" type of unit that changes the configuration of other units. However, as it seems, systemd ignores such changes until I use daemon-reload...<br></blockquote><div><br></div><div>Yes. you need an explicit daemon-reload here.</div><div>why can't it be a real generator ?</div><div><br></div><div>could you use systemd-run or the equivalent dbus API to do what you are trying to do ?</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
