The branch stable/12 has been updated by eugen: URL: https://cgit.FreeBSD.org/src/commit/?id=85c1418ba1c827a73c04689fceb4edd1ab0eea64 commit 85c1418ba1c827a73c04689fceb4edd1ab0eea64 Author: Eugene Grosbein <eugen@FreeBSD.org> AuthorDate: 2023-07-03 12:35:37 +0000 Commit: Eugene Grosbein <eugen@FreeBSD.org> CommitDate: 2023-07-18 08:07:04 +0000 syslog.3: MFC: document ident[N] format When libc switched to generation of logs as per RFC 5424, that change broke application ability to insert specific process id using ident[N] format, the feature existed for decades. Some processes rely on it (including logger and syslogd). Later the regression was fixed but the feature remained undocumented. This change documents it.
