/*
 * openrc — the service manager / init system (first init).
 *
 * kappa generates openrc service files (boot.init = "openrc") — this
 * package provides the manager itself: openrc-init, openrc-run,
 * rc-update, start-stop-daemon, plus the /etc/init.d + runlevel layout.
 *
 * BUILD REQUIREMENTS: meson + ninja + python + pkg-config (all kappa
 * packages, prepended to PATH).  Optional deps (pam/audit/selinux) are
 * disabled for barebones compatibility.
 *
 * ROOT HANDOFF (kappa has no activation step yet)
 * ==============================================
 * The store cannot boot anything by itself.  To actually boot this init:
 *   cp -a <store>/bin/<hash>/sbin/. /sbin/
 *   cp -a <store>/bin/<hash>/bin/.  /bin/
 *   cp -a <store>/bin/<hash>/lib/.  /lib/
 *   cp -a <store>/bin/<hash>/etc/init.d /etc/
 *   cp -a <store>/bin/<hash>/etc/conf.d /etc/
 * then set `init=/sbin/openrc-init` on the kernel command line.
 * kappa's rebuild writes generated service scripts into /etc/init.d.
