    (description
     "The primary goal of this project is to define a portable and efficient C
programming interface (API) to determine the call-chain of a program.  The API
additionally provides the means to manipulate the preserved (callee-saved)
state of each call-frame and to resume execution at any point in the
call-chain (non-local goto).  The API supports both local (same-process) and
remote (across-process) operation.  As such, the API is useful in a number of
applications.")

refresh interval but that is outside the range of RFC 1912, which is
entitled "Common DNS Operational and Configuration Errors." [1]

Section 2.2 of RFC 1912 recommends a maximum of 12 hours for the SOA
refresh rate: "You can keep it short (20 mins to 2 hours) if you
aren't worried about a small increase in bandwidth used, or longer
(2-12 hours) if your Internet connection is slow or is started on
demand."

This commit sets the default refresh interval at the nearest value
recommended by the standard, which is 12 hours.

Due to the widespread adoption of NOTIFY messages between primary and
secondary DNS servers, the SOA refresh interval has arguably lost some
importance, but the Guix default should still be in line with the
standards.

Values outside the recommended range can provoke warning messages from
services commonly used to find bugs in DNS configurations, such as the
MX Toolbox Super Tool. [2]
