       /sbin/blogd [/dev/realtty]


       Without  argument  blogd  determines  the  real underlying
       character device of /dev/console.  blogd spawns a  pty/tty
       pair  to reconnect the current /dev/console with the slave
       of the pty/tty pair. During writing information from  this
       slave  to  the real character device a ring buffer is used
       to hold the information for writing it to an existing log­
       ging file.

       To fetch the real tty of /dev/console the program showcon­
       sole(8) can be used. This has  the  advantage  that  blogd
       will not hold the real character device of /dev/console as
       its controlling tty (would hangup  any  running  getty  on
       that character device).


       blogd knows a few signal to contol its behavior.

              will cause blogd tries to write out the ring buffer
              and to exit.

       SIGIO  says  blogd  that  now  it  is  able  to  write  on
              /var/log/boot.msg  which means that the file system
              is mounted read/write and the kernel  messages  are
              written to that file.


       blogd  needs  a mounted /proc and /dev/pts file system and
       tries to set the controlling tty  to  stdin  if  the  real
       character  device  of  /dev/console  is  not given.  After
       reading /proc blogd tries to restore  the  status  of  the
       controlling  tty  to  avoid problems with getty processes.
       This can fail because blogd forks to run in the background
       as a daemon.


       /proc/<pid of blogd>/stat
              the stat file of the blogd process.

              the system console.

              logging  file  which  is  created  by  klogd(8)  or


       showconsole(8), syslogd(8), klogd(8), dmesg(8), proc(5).
