runit-init(8)                                                 System Manager's Manual                                                runit-init(8)

NAME

       init - a UNIX process no 1

SYNOPSIS

       init [ 0 | 6 ]

DESCRIPTION

       runit-init is the first process the kernel starts.  If runit-init is started as process no 1, it runs and replaces itself with runit(8).

       If runit-init is started while the system is up, it must be either called as init 0 or init 6:

       init 0 tells  the  Unix  process  no 1 to shutdown and halt the system.  To signal runit(8) the system halt request, runit-init removes all
              permissions of the file /etc/runit/reboot (chmod 0), and sets the execute by owner permission of the file  /etc/runit/stopit  (chmod
              100).  Then a CONT signal is sent to runit(8).

       init 6 tells  the  Unix  process no 1 to shutdown and reboot the system.  To signal runit(8) the system reboot request, runit-init sets the
              execute by owner permission of the files /etc/runit/reboot and /etc/runit/stopit  (chmod  100).  Then  a  CONT  signal  is  sent  to
              runit(8).

EXIT CODES

       runit-init returns 111 on error, 0 in all other cases.

NAME

       runsvdir - starts and monitors a collection of runsv(8) processes

SYNOPSIS

       runsvdir [-P] dir [ log ]

DESCRIPTION

       dir must be a directory.  log is a space holder for a readproctitle log, and must be at least seven characters long or absent.

       runsvdir  starts  a runsv(8) process for each subdirectory, or symlink to a directory, in the services directory dir, up to a limit of 1000
       subdirectories, and restarts a runsv(8) process if it terminates.  runsvdir skips subdirectory names starting with dots.  runsv(8) must  be
       in runsvdir's PATH.

       At  least every five seconds runsvdir checks whether the time of last modification, the inode, or the device, of the services directory dir
       has changed.  If so, it re-scans the service directory, and if it sees a new subdirectory, or new symlink to a directory, in dir, it starts
       a  new  runsv(8)  process;  if  runsvdir  sees  a subdirectory being removed that was previously there, it sends the corresponding runsv(8)
       process a TERM signal, stops monitoring this process, and so does not restart the runsv(8) process if it exits.

       If the log argument is given to runsvdir, all output to standard error is redirected to this log, which  is  similar  to  the  daemontools'
       readproctitle  log.   To  see the most recent error messages, use a process-listing tool such as ps(1).  runsvdir writes a dot to the read-
       proctitle log every 15 minutes so that old error messages expire.

OPTIONS

       -P     use setsid(2) to run each runsv(8) process in a new session and separate process group.

SIGNALS

       If runsvdir receives a TERM signal, it exits with 0 immediately.

       If runsvdir receives a HUP signal, it sends a TERM signal to each runsv(8) process it is monitoring and then exits with 111.
