From options(4):
     options MSGBUFSIZE=integer
     This option sets the size of the kernel message buffer.  This buffer
     holds the kernel output of printf() when not (yet) read by syslogd(8).
     This is particularly useful when the system has crashed and you wish to
     lookup the kernel output from just before the crash.  Also, since the au-
     toconfig output becomes more and more verbose, it sometimes happens that
     the message buffer overflows before syslogd(8) was able to read it.  Note
     that not all systems are capable of obtaining a variable sized message
     buffer.  There are also some systems on which memory contents are not
     preserved across reboots.
