Currently, it doesn't compose, but can it be made composable? More concretely, maybe there could be a set of =E2=80=98process procedures= =E2=80=99 implementable by record types: ;; Inspired by , ;; with some differences (define (subprocess-start/separate process) ...) ; run it in a separate = process (define (subprocess-start/replace process) ...) ; run it with 'exec' (define (subprocess-kill process) ...) (define (subprocess-wait process) ...) (define (subprocess-status process) ...) ;; Basic process constructor, doesn't do containers (define (command-process ...) ...) ;; Container (define (contain inner #:key container-stuff ...) subprocess-start/separate: (run-container ... (lambda () (subprocess-st= art/replace inner))) other procedures ... return the record) Then make-inetd-constructor could be changed to accept a lambda producing 'subprocess' records. By passing it a subprocess wrapped by 'contain', it = would automatically support container things: (define (make-inetd-constructor/container-command command* ...) (make-inetd-constructor (lambda () (contain (command-process comand*))) .= ..))
