42.2.5 Adding a new configuration
setting on the fly
Besides overriding existing settings in the configuration
file, you can use a configuration-variable assignment to specify a persistent
override for a setting that is not even present in your configuration
file, provided both of the following are true:
- [Section] is listed as subject to
overrides in one of Table
42-2 through Table 42-6.
- Key is a valid key
for the section.
If the section is not listed, or the key is not valid
for the section, the setting you specify is treated instead as an error,
with value “0” (zero).
