I think we could split 19.1.2 in two parts, where the first one is the
current content minus the paragraph "The configuration file is reread".
We'd create "19.1.3 Configuration File Reloads" to contain that
paragraph, perhaps not with the exact current wording.

Dunno. Given that other configuration elements such as config file
placement are already in chapter 19, it seems strange to put reloading
behavior in 18.
