runsvdir

runsvdir [-P] dir [log]

runsvdir starts and monitors a collection of runsv(8) processes. It scans dir at least every five seconds. When a new subdirectory or symlink to a directory appears, runsvdir starts a new runsv process for it. When a subdirectory is removed, the corresponding runsv process is sent a TERM signal.Subdirectories whose names start with a dot are ignored. The maximum number of services is 1000.Sending runsvdir a TERM signal causes it to exit with status 0. Sending a HUP signal causes it to send TERM to all running runsv processes and then exit with status 111.

-P

Use setsid to run each runsv process in a new session and separate process group.

Service directory to monitor. Each subdirectory (or symlink to a directory) is started as a supervised service via runsv.

Optional log command. If specified (must be at least seven characters), runsvdir pipes its error output through this command, similar to daemontools' readproctitle.

- Create symlink in dir: service starts automatically on next scan- Remove symlink: service stops via TERM signal- Use the sv command to control individual services

Usually started by runit init at system boot. The filesystem should not be unmounted while runsvdir is running. Permissions on service directories must be correct for runsv to start.

runsvdir is the service directory supervisor in runit, created by Gerrit Pape. It watches for service directories and manages runsv processes for each.
