  • Note that s6-notifyoncheck should be used to check if the current service itself is running. You cannot use it to poll for the readiness of another service.

  • s6-notifyoncheck must be run with the service directory as its +current working directory. In other words: you cannot use cd +in your run script before you execute the command line containing +s6-notifyoncheck (else you will get a weird error message saying the +supervisor is not running). If your service needs to run in a different +working directory, you need to change working directories after +the s6-notifyoncheck invocation. The +cd utility from +the execline package +can be used to change working directories in the middle of a command +line (and exec the rest of the command line) without invoking a shell.
