New Revision: 338334
URL: https://svnweb.freebsd.org/changeset/base/338334
Log:
MFC r336086:
Use the FQDN in the newsyslog log message when RFC 5424 is enabled.
The RFC 5424 spec mentions that logging FQDNs over short hostnames is
preferred. Alter this code, so that the hostname doesn't get truncated
on startup. Keep track of the length of the short hostname, so that
fprintf() can do the truncation where necessary.
