mgetty will normally write all actions into a logfile, named
LOG_PATH.<device> (LOG_PATH is defined policy.h),
e.g. /var/log/mgetty.ttyxx, so you can easily see what’s happening in your
system. (If a fatal error
occurs, the error message is also written to the console, and if that
is not possible, mailed to ‘ADMIN’). The name of the log file can be
changed in policy.h.
If mgetty is compiled with -DSYSLOG, auditing and error log
messages will also go to syslog (if your system supports it).
