For cases where the constant must be used, there are two values: 64 and 256. The smaller value is compatible with current releases and is
used by default. To use the larger value consult the related documentation (see nodehostnamesize(5)).
The administrator may, with appropriate configuration options enabled, set a host name larger than 64 bytes. Existing applications which
were compiled using the smaller to size a buffer passed to the system function obtain only the first 64 bytes. This truncation may cause
the applications to exhibit anomalous behavior or to fail.
