Supervisor scripts modify the global variable extra_commands, even if the supervisor is not used.

[linsein]

Environment

alpine linux 3.24.0_alpha20251224
openrc 0.63-r1

Reproduction

#!/sbin/openrc-run

name="demo"
command="true"

$ ./demo reload
/usr/libexec/rc/sh/openrc-run.sh: line 224: s6-svc: not found

Analysis

openrc-run.sh.in always imports supervisor scripts:

openrc/sh/openrc-run.sh.in

Lines 261 to 265 in a951b9a

	# load service supervisor functions
	sourcex "@LIBEXECDIR@/sh/runit.sh"
	sourcex "@LIBEXECDIR@/sh/s6.sh"
	sourcex "@LIBEXECDIR@/sh/start-stop-daemon.sh"
	sourcex "@LIBEXECDIR@/sh/supervise-daemon.sh"

s6.sh changes the default extra_commands:

openrc/sh/s6.sh

Line 25 in a951b9a

extra_commands="restart reload ${extra_commands}"

commands defined only for s6 supervisor:

openrc/sh/s6.sh

Lines 225 to 233 in a951b9a

	restart() {
	_s6_set_variables
	s6-svc -r -- "$_service"
	}
	reload() {
	_s6_set_variables
	s6-svc -h -- "$_service"
	}

also in supervise-daemon.sh:

openrc/sh/supervise-daemon.sh

Line 13 in a951b9a

extra_commands="healthcheck unhealthy ${extra_commands}"
