include:
- Extend the syntax of syslog.conf to allow selections of log destinations
by comma-separated lists of program name (including kernel-generated
messages) and originating host name.
- Ability to pipe selected messages through arbitrary filter commands.
- Ability to specify priority comparison operations.
- Improvements to domain name handling.
- Conversion to use kqueue for communication and signal events, eliminating
all unsafe signal handlers.
- Allow spaces as well as tabs in syslog.conf.
- Log kernel printfs at LOG_NOTICE instad of LOG_CRIT.
- Ability to log facility/priority with a log message.
- Reliability improvements.
This avoids some seriously gratuitous disk hosage in various cases.
XXX It would probably be better to allow this to be specified in the config
file somehow.
the same string into "last message repeated N times", and instead forces
syslogd to write out every message.
Based on '-c' in FreeBSD's syslogd, although a different option letter was
chosen because their syslogd requires '-c -c' to get this functionality,
and we don't have the support for logging to pipes which is what FreeBSD's
syslogd with a single '-c' is related to.
stdout before syslogd becomes a daemon.
- Flags for setuid/setgid/chroot syslogd after initialization is completed
- Warning instead of silent ignoring for malformed lines (with spaces instead
of tags)

request:
instead of the -S flag, fix the -s flag to not open a socket
if there are no forwarding rules in /etc/syslog.conf
The behavior of syslogd when -s is specified and there are forwarding rules
should still be made cleaner.
in man page and comments -- for some time it has no longer prevents
an inet socket from being opened, just caused it to be ignored
2.) Fix this problem with `-s' -- syslogd always opens an inet socket, even if
-s is specified and it has nowhere to send to. This socket is then
shutdown(), but there is no way to not have this socket open.
Users setting up paranoid installations can now specify `-S' which
prevents any non-unix-domain sockets from being opened, even if
forwarding is specified in /etc/syslogd.conf.
As per the previous fix, this is not made the default for `-s', as it
also prevents syslogd from forwarding log messages.
3.) document the above in the man page and usage.
Justification: in light of the possibility of future DoS attacks, or the
desire to set up a machine which is relatively uninformative in the face
of port scans, users may quite legitimately want to control what sockets
are open on their machine. Telling such users that they cannot run
syslogd is non-ideal.
if given this). this is extremely useful for chrooted daemons that
still want to create log entries via a local mechanism.
- create a new -P option that takes a filename of log sockets (equiv.
of calling syslogd which -p <each line of file>. this is useful
for the case of many chroot areas and keeping this information in
one place rather than having to remember it all.
if no -p options are given, the default (_PATH_LOG) is used as normal.
