This is rather sparse documentation of the knob. If I were a regular sysadmin I probably wouldn't know if I want to tweak this or not. On the other hand, we don't want regular sysadmins to touch this :-)
I've experienced just a few timeout related issues in the past on the nodes I manage. At that time, I adjusted this knob and temporarily surpassed it. Note that the essential problem appears to have been fixed in the master branch.
So this wil set the timeout globally. Meaning, if I start a domain it will by default use 30 seconds timeout. But then, if I'd change the config and restart the daemon the domain would use the new value. On the other hand, that might not be necessary. So if you send the expanded comment for the knob then I can merge these.
Yes, this knob is applied to all domains when the libivrtd process is restarted, as you said. However, I don't understand exactly how this knob will affect the entire system. So, this knob worked well in my environment, but may not be needed in other users' environments.
