So let's upgrade another jail, which needs an update.

#### Configuration processing functions
#-
# Configuration options are set in the following order of priority:
# 1. Command line options
# 2. Configuration file options
# 3. Default options
# In addition, certain options (e.g., IgnorePaths) can be specified multiple
# times and (as long as these are all in the same place, e.g., inside the
# configuration file) they will accumulate. Finally, because the path to the
# configuration file can be specified at the command line, the entire command
# line must be processed before we start reading the configuration file.
#
# Sound like a mess? It is. Here's how we handle this:
# 1. Initialize CONFFILE and all the options to "".
# 2. Process the command line. Throw an error if a non-accumulating option
# is specified twice.
# 3. If CONFFILE is "", set CONFFILE to /etc/freebsd-update.conf .
# 4. For all the configuration options X, set X_saved to X.
# 5. Initialize all the options to "".
# 6. Read CONFFILE line by line, parsing options.
# 7. For each configuration option X, set X to X_saved iff X_saved is not "".
# 8. Repeat steps 4-7, except setting options to their default values at (6).
