Creating them with the wrong group, wrong chmod bits, or not
including 'nosave' on logfiles which are expected to be
'nosave' might be a problem.

You don't want to rotate logfiles on an embedded system?

To use this new syslogd feature, you're going to have to add
that '-C' flag somewhere. And in /etc/defaults/rc.conf, we
newsyslog_enable="YES" # Run newsyslog at startup.
newsyslog_flags="-CN" # Newsyslog flags to create marked files
All you need to do is add a second '-C' to those newsyslog_flags,
and newsyslog will automatically create all log files which do
not exist. And if you're adding a new logfile to /etc/syslog.conf,
then it seems to is very likely that you will also want to add a
line to newsyslog.conf to rotate that log file.

I believe newsyslog will correct those the next time it rotates
the logfile. I'm not sure it should add code to fix files that
are wrong only because some operation other than newsyslog
created the file, but I suspect it would be easy enough to add
that if people really think it is important.
