#!/usr/bin/env bash
## entrypoint-litespeed.sh — PID 1 for cac-litespeed:phpNN.
## Built on litespeedtech/openlitespeed:1.8.x-lsphp83 prebuilt base. Native
## LSAPI (no FPM proxy), one customer per container.
##
## Process supervision: starts OLS via `openlitespeed -n` (no-daemon +
## crash-guard, per OLS source: lshttpdmain.cpp). SIGTERM is forwarded.
## crond runs in the background for customer crontabs; OLS itself is the
## process we wait on (if OLS dies, the container exits and Docker
## restarts it per its restart policy).
