If the environment doesn't offer a working /dev/console, the existing
version of init(8) will simply refuse running rc(8) scripts. This means
you'll only have a system running init(8) and nothing else.
Change the code to do the following:
- Open /dev/console like we used to do, but make it more robust to use
O_NONBLOCK to prevent blocking on a carrier.
- If this fails, use /dev/null as stdin and /var/log/init.log as stdout
and stderr.
- If even this fails, use /dev/null as stdin, stdout and stderr.
So why us this useful? Well, if you remove the `getpid() == 1' check in
main(), you can now use init(8) inside jails to properly execute rc(8).
It still requires some polishing, as existing tools assume init(8) has
PID 1.
Also it is now possible to use use init(8) on `headless' devices that
don't even have a serial boot console.
does ever come back it's probably best if its log file be something that
gets added if the user decided they want to run slip instead of having
it here unconditionally.
- Enable it by default, running newsyslog with -CN which creates files
that have the C flag specified in /etc/newsyslog.conf.
- Remove the "newsyslog -CC" call from etc/rc.d/var and the check for
newsyslog.
- Add the C flag to entries in /etc/newsyslog.conf that are currently
installed as part of the base system.
There are two effects from this change:
- Users who delete default syslog files to stop logging to them
will need to set newsyslog_enable=NO in rc.conf or remove the C
flag from those file in /etc/newsyslog.conf or they will come back
on the next boot.
- Diskless systems now create the same set of files that ordinary
systems have by default instead of every file in newsyslog.conf.
o Introduce /var/log/authentication.log, which will be the target for
auth.info and authpriv.info by default. Rotate on the same schedule
as most other logs. Create at installation.
o Remove logging of auth.info from /var/log/security.log, which will
return to being only for security feature subsystems (such as ipfw,
and so on).
This creates a special authentication log, which can now be searched
by scripts for authentication events.

get changed in future revisions.
default syslog target for console messages (when enabled in
syslog.conf). Use the same rotation defaults as with
/var/log/messages -- every 100kb of log, compress back logs,
and keep five rotated logs.
o Note: phk also thought it would be useful to force rotation
each boot. This commit does not introduce such a rotation.

All periodic sub-scripts <larf> now have their return codes interpreted
by periodic(8). Output may be masked based on variable values in
periodic.conf.
It's also now possible to email periodic output to arbitrary addresses,
or to send it to a log file, examples of which can be found in
newsyslog.conf.
The upshot of it all should be no discernable changes to the default
behaviour of periodic(8).

wheel to trash logfiles is not exactly good security policy. There have
been several gid wheel holes in ports. Various other files were changed
as well (eg: the locate database were set to more restrictive modes (444)
by their generation scripts) so this should be safe for them. utmp and
wtmp are mode 644 already on all the systems we checked.

an all.log for logging all messages, and one to demonstrate use of loghosts.
Also, a matching entry in newsyslog.conf for all.log.
Per request of Garrett Wollman, also modified the maillog entry to use the
@T newsyslog time specification mechanism. Because newsyslog doesn't
support the mod date specification machanism, couldn't change other
entries that required more than one execution a month, but less than once
a day.

let it rotate /var/log/wtmp again, and update monthly/200.accounting to
take this into account. (Some sites might want to change the parameters
of the rotation; it's easier to do this when it's all centralized in
newsyslog.conf.)
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
