svscanboot.8

NAME

svscanboot - start svscan in service directories, with output/error logged through multilog.

SYNOPSIS

svscanboot [ servicedir ]

DESCRIPTION

svscanboot (without any command-line arguments) runs svscan command

svscan /service 2>&1

If svscanboot is given a command-line argument, it starts up svscan for the directory servicedir given on the command line (instead of just svscan /service).

svscanboot uses envdir(8) on servicedir/.svscan/variables to set environment variables and clear all other environment variables.

You can set the following typical variables in servicedir/.svscan/variables directory

 PATH
 SCANINTERVAL  - If set, svscan(8) uses this to look for new services every
                 SCANINTERVAL seconds.
 STATUSFILE    - Used by svscan(8)
 INITCMD       - If set, svscan(8) runs this command using /bin/sh, before
                 running supervise(8).
 WAIT_INITCMD  - If set, svscan(8) waits for this INIT_CMD to finish before
                 starting supervise(8)
 SCANLOG       - If set, svscan(8) logs all messages and errors using
                 multilog with instructions in
                 servicedir/.svscan/log/run. If not set,
                 svscanboot(8) pipes stdout, stderr of svscan(8) to
                 readproctitle(8)
 UNSHARE       - If set, svscanboot(8) uses unshare --mount command to run
                 svscan(8)

The recommended old way was to put the following entry in /etc/inittab to invoke svscanboot.

SV:345:respawn:/usr/libexec/indimail/svscanboot <>/dev/console 2<>/dev/console

Many of the current operating systems use systemd(1) replacement for init(1). svcanboot(8) should be invoked by your boot scripts - systemd(1), upstart(1), init(1) or boot rc scripts.
